                                 PROXY STATEMENT

Deadline for Receipt of Stockholder Proposals

    Stockholders of the Company may submit proper proposals for inclusion in the
Company's proxy statement and for consideration at the next annual meeting of
stockholders by submitting their proposals in writing to the Secretary of the
Company in a timely manner. In order to be considered for inclusion in the
Company's proxy materials for the annual meeting of stockholders to be held in
the year 2003, stockholder proposals must be received by the Secretary of the
Company no later than December 5, 2002, and must otherwise comply with the
requirements of Rule 14a-8 of the Securities Exchange Act of 1934, as amended
(the "Exchange Act").

    In addition, the Company's bylaws establish an advance notice procedure with
regard to business brought before an annual meeting, including stockholder
proposals not included in the Company's proxy statement. For director
nominations or other business to be properly brought before the 2003 Annual
Meeting by a stockholder, such stockholder must deliver written notice to the
Secretary of the Company at the Company's principal executive office no later
than February 3, 2003 and no earlier than January 4, 2003. If the date of the
Company's 2003 Annual Meeting is advanced or delayed by more than 30 calendar
days from the first anniversary date of the 2002 Annual Meeting, your notice of
a proposal will be timely if it is received by the Company by the close of
business on the tenth day following the day the Company publicly announces the
date of the 2003 Annual Meeting.

    The Proxy grants the proxy holders discretionary authority to vote on any
matter raised at the Annual Meeting. If such a stockholder fails to comply with
the foregoing notice provisions, proxy holders will be allowed to use their
discretionary voting authority should the stockholder proposal come before the
2003 Annual Meeting.

    A copy of the full text of the bylaw provisions governing the notice
requirements set forth above may be obtained by writing to the Secretary of the
Company. All notices of proposals and director nominations by stockholders
should be sent to National Instruments Corporation, 11500 N. Mopac Expressway,
Building B, Austin, Texas 78759, Attention: Corporate Secretary.

                                       2



                                  PROPOSAL ONE:

                              ELECTION OF DIRECTORS

General

    The Company's Board of Directors is divided into three classes, with the
term of office of one class expiring each year. The Company currently has seven
directors with two directors in two classes and three directors in one class.
The terms of office of Class II directors L. Wayne Ashby and Donald M. Carlton
will expire at the 2002 Annual Meeting. Mr. Ashby is not standing for
re-election at the 2002 Annual Meeting. Dr. Carlton will stand for re-election
to the Board of Directors at the 2002 Annual Meeting. In addition, Jeffrey L.
Kodosky, whose term of office expires at the 2003 Annual Meeting, has tendered
his resignation from the Board of Directors to take effect immediately prior to
the 2002 Annual Meeting. Mr. Kodosky will stand for re-election to the Board of
Directors at the 2002 Annual Meeting. The terms of office of Class III directors
Ben G. Streetman and R. Gary Daniels will expire at the 2003 Annual Meeting and
the terms of office of Class I directors James J. Truchard and Charles J.
Roesslein will expire at the 2004 Annual Meeting. At the 2002 Annual Meeting,
stockholders will elect two directors for a term of three years. After the
election at the 2002 Annual Meeting, there will be six directors, with two
directors in each of the three classes.

Vote Required

    The two nominees receiving the highest number of affirmative votes of the
shares present in person or represented by proxy at the Annual Meeting and
entitled to vote in the election of directors shall be elected to the Board of
Directors. Votes withheld from any director are counted for purposes of
determining the presence or absence of a quorum, but have no legal effect under
Delaware law. While there is no definitive statutory or case law authority in
Delaware as to the proper treatment of abstentions and broker non-votes in the
election of directors, the Company believes that both abstentions and broker
non-votes should be counted for purposes of whether a quorum is present at the
Annual Meeting. In the absence of precedent to the contrary, the Company intends
to treat abstentions and broker non-votes with respect to the election of
directors in this manner. Cumulative voting is not permitted by the Company's
Certificate of Incorporation.

    Unless otherwise instructed, the proxy holders will vote the proxies
received by them for the Company's two nominees named below. If any nominee of
the Company is unable or declines to serve as a director at the time of the
Meeting, the proxies will be voted for any nominee who is designated by the
present Board of Directors to fill the vacancy. It is not expected that any
nominee will be unable or will decline to serve as a director. The Board of
Directors recommends that stockholders vote FOR the nominees listed below.

    The following sets forth information concerning the nominees for election as
directors at the Annual Meeting, including information as to each nominee's age

(1)  The dollar amounts under these columns are the result of calculations at
     the 5% and 10% rates set by the SEC and therefore are not intended to
     forecast possible future appreciation, if any, of the Company's stock
     price. The Company did not use an alternative formula for a grant date
     valuation, as the Company does not believe that any formula will determine
     with reasonable accuracy a present value based on future unknown or
     volatile factors.

(2)  These options have a term of ten years and vest as to 1/120th of the shares
     per month after the date of grant, subject to acceleration based upon
     Company financial performance.

(3)  These options are subject to a maximum of twelve months of accelerated
     vesting if the optionee's employment is constructively terminated or
     terminated without cause within three years of his hire date.

Compensation Committee Interlocks and Insider Participation

     In 2001, the Compensation Committee consisted of directors R. Gary Daniels,
Ben G. Streetman, L. Wayne Ashby and Charles J. Roesslein. Dr. Truchard may
participate in the deliberations of the Compensation Committee with respect to
the compensation of the Company's executive officers (other than himself),
changes in the incentive plan and in other compensation matters.

Section 16(a) Beneficial Ownership Reporting Compliance

     Section 16(a) of the Exchange Act requires the Company's officers and
directors, and persons who own more than 10% of a registered class of the
Company's equity securities, to file reports of ownership on Form 3 and changes
in ownership on Form 4 or Form 5 with the SEC. Such officers, directors and 10%
stockholders are also required by SEC rules to furnish the Company with copies
of all Section 16(a) forms they file. Based solely on its review of the copies
of such forms received by it, the Company believes that, during the fiscal year
ended December 31, 2001, all Section 16(a) filing requirements applicable to its
officers, directors and 10% stockholders were satisfied.

Performance Graph

     The following line graph compares the cumulative total return to
stockholders of the Company's Common Stock from March 13, 1995 (the date of the
Company's initial public offering) to December 31, 2001 to the cumulative total
return over such period of the (i) Nasdaq Composite Index and (ii) Russell 2000
Index. The graph assumes that $100 was invested on March 13, 1995 in the
Company's common stock at its initial public offering price of $6.44 per share
and in each of the other two indices and the reinvestment of all dividends, if
any. Stockholders are cautioned against drawing any conclusions from the data
contained therein, as past results are not necessarily indicative of future
performance.

     The information contained in the Performance Graph shall not be deemed to

information be incorporated by reference into any future filing under the
Securities Act of 1933, as amended (the "Securities Act"), or the Exchange Act,
except to the extent that the Company specifically incorporates it by reference
into any such filing. The graph is presented in accordance with SEC

     Report of the Compensation Committee Regarding Executive Compensation*

    The Compensation Committee, composed of directors Daniels, Streetman, Ashby
and Roesslein, is responsible for determining the compensation programs and
levels of pay for the Company's executive officers. The Committee also advises
management on pay programs and levels for other employees. The Committee
utilizes independent survey data for analyses of competitive industry pay levels
and practices, and to guide the Committee on appropriate pay levels for the
Company.

    Compensation Philosophy and Objectives. The Company's basic philosophy is to
align executive compensation with increases in stockholder value through growth
in sales and operating profits. Primarily, this is accomplished through the use
of stock options, which provide compensation in direct proportion to increases
in stockholder value, and profit sharing. In addition, the Company believes it
is important to emphasize teamwork, entrepreneurship and active participation by
all employees. This is accomplished through providing options to a majority of
full-time, exempt domestic employees and similarly situated international
employees, and through cash incentives, through which both executive and other
employees receive cash bonuses based on company-wide financial goals. Finally,
it is the Company's philosophy that no special perquisites should be provided to
senior executives.

    Executive Compensation Programs. The Company's executive compensation
programs consist of three principal elements: base salary, cash bonus and stock
options. The Company emphasizes incentive compensation in the form of stock
options and bonuses, rather than base salary. The Compensation Committee has
adopted a guideline that executives should be paid competitive base salaries.
The Committee sets the annual base salary for executives. Prior to making its
determination, the Compensation Committee reviews historical compensation levels
of the executives, evaluations of past performance, assessments of expected
future contributions of the executives, competitive pay levels and programs
provided by other comparable companies, and general industry pay practices. In
making its determinations, the Committee does not utilize any particular indices
or formulae to arrive at each executive's recommended pay level. In a
demonstration of leadership during the economically challenging times of 2001,
the executive officers proposed that the Company temporarily reduce their base
salaries. In response, the base salary of each executive officer, except the
Vice President of Sales, was adjusted to reflect a 5% reduction effective
October 1, 2001.

    For many years, the Company has maintained a cash bonus plan under which
executive officers participate. In recent years, this plan provided for a target
incentive to be paid based on achieving pre-determined levels of revenue growth
and profitability. For fiscal 2001, 2000 and 1999 these goals were 40% revenue
growth and 18% operating profit as a percent of revenue, the same goals as for
all other employees. At the end of each year, actual results for the Company are
compared to these targets and executive bonuses are based on actual Company
performance in relation to these factors. If there is no growth or no
profitability, no cash bonuses are payable to executive officers. Individual
performance is not considered in determining the bonus of individual officers
for the cash bonus program.

    In 1999, the Company added a discretionary cash bonus program for
executive officers and other employees which is funded based upon the
achievement of the Company's minimum quarterly growth goal and with payments
based upon individual performance. The program was adjusted as of the second
quarter of 2000 to provide that if the Company meets its minimum quarterly
revenue growth goal, a percentage of payroll will be available as a
discretionary cash bonus pool for distribution to executive and other employees.
For fiscal year 2001, the minimum quarterly growth goal was 20% revenue growth
over the same period in the prior year. As a result of the program, executives
and other employees are eligible to receive the discretionary cash bonus on a
quarterly basis. Separate from the discretionary cash bonus program, in December
2001, the Company paid each executive officer, except Dr. Truchard, a bonus
award of approximately $1,400 in appreciation of their management efforts
throughout fiscal year 2001. In addition, the Vice President, Sales is eligible
for a separate company sales commission program based upon growth and
profitability performance measures approved by the Board of Directors.

    Total compensation for executive officers also includes long-term
incentives in the form of stock options, which are generally provided through
initial stock option grants at the date of hire and periodic additional stock
option grants. Stock options are instrumental in promoting the alignment of
long-term interests between the Company's executive officers and stockholders
due to the fact that executives realize gains only if the stock price increases
over the fair market value at the date of grant and the executives exercise
their options. In determining the amount of such grants, the Committee evaluates

                                       12



the job level of the executive, responsibilities of the executive, and
competitive practices in the industry. All options are granted at 100% of fair
market value at the date of grant. Options to executive officers and other
employees vest over a period of five years or ten years, subject to acceleration
based on Company performance (in case of special option grants to executives);
however, Mr. Ravel also has the right to a maximum of twelve months of
accelerated vesting of his stock holdings if his employment is constructively
terminated or terminated without cause within three years of his hire date. The
long-term value realized by executives through option exercises can be directly
linked to the enhancement of stockholder value.

     Chief Executive Officer Compensation. While the Board was highly pleased
with Dr. Truchard's performance in 2001, at his request, the Chief Executive
Officer's base salary was reduced along with other executive officers (as
discussed above), and he received no stock options. Based on the same formula
applied to other executive officers, Dr. Truchard did not receive a bonus for
2001 and declined to receive the $1,400 bonus awarded to the other executive
officers. Dr. Truchard is the Company's largest stockholder with an ownership of
approximately 25% of the Company's stock.

     Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"), imposes a limit on tax deductions for annual compensation in excess of
one million dollars paid by a corporation to its chief executive officer and the
other four most highly compensated executive officers of a corporation.
Deductions are, however, permitted if certain conditions are met, including a
requirement that the plan under which such compensation is paid be reapproved by
stockholders every five years. None of the compensation paid by the Company in
fiscal 2001 was subject to the limitation on deductibility. The Compensation
Committee will continue to assess the impact of Section 162(m) of the Code on
its compensation practices and determine what further action, if any, is
appropriate.

                                                    Respectfully Submitted,


                                                    R. Gary Daniels

                         Report of the Audit Committee*

     The Audit Committee is composed of four independent directors and operates
under a written charter adopted by the Board of Directors. The members of the
Audit Committee are Donald M. Carlton, Chairman, Ben G. Streetman, R. Gary
Daniels and Charles J. Roesslein. All members of the Audit Committee meet the
independence standards of Rule 4200(a)(15) of the National Association of
Securities Dealers' listing standards.

     In March 2002, the Board of Directors amended the Committee's charter to
incorporate restrictions on the use of the Company's independent auditor,
PricewaterhouseCoopers LLP, to provide non-audit services. (The amended charter
is attached to this proxy as Appendix A.)

     Management is responsible for National Instruments' internal controls and
the financial reporting process. National Instruments' independent auditors are
responsible for performing an independent audit of National Instruments'
consolidated financial statements in accordance with generally accepted auditing
standards and to issue a report thereon. The Audit Committee's responsibility is
to monitor and oversee these processes.

     The Committee schedules its meetings and conference calls with a view to
ensuring it devotes appropriate attention to all of its tasks. The Committee
convened 11 times during fiscal 2001 to carry out its responsibilities. The
Committee regularly meets privately with the independent auditors, internal
audit, and management, each of whom has unrestricted access to the Committee.

     As part of its oversight of the Company's financial statements, the
Committee reviewed and discussed with both management and the independent
auditors the Company's quarterly and audited fiscal year financial results,
including a review of National Instruments' Annual Report on Form 10-K. The
Committee also discussed with the independent auditors any matters required to
be discussed by Statement on Auditing Standards No. 61, Communication with Audit
Committees, as amended.

     The Audit Committee has also received the written disclosures from
PricewaterhouseCoopers required by Independence Standards Board Standard No. 1
(Independence Discussions with Audit Committees), and the Audit Committee has
discussed the independence of PricewaterhouseCoopers with that firm. The
Committee has implemented a procedure to monitor auditor independence.

     Based upon the Audit Committee's discussion with management and
PricewaterhouseCoopers and the report of PricewaterhouseCoopers to the Audit
Committee, the Audit Committee recommended that the Board of Directors include
the audited consolidated financial statements in National Instruments' Annual
Report on Form 10-K for the year ended December 31, 2001, which was filed with
the SEC.

                                     Charles J. Roesslein

* The foregoing Report of the Audit Committee does not constitute soliciting
material and should not be deemed filed or incorporated by reference into any
other Company filing under the Securities Act of 1933 or the Securities Exchange
Act of 1934, except to the extent the Company specifically incorporates this
Report by express reference therein.

                                       14



                                  PROPOSAL TWO:
                  APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

     The Board of Directors, upon the recommendation of its Audit Committee, has
appointed, subject to approval by the Company's stockholders,
PricewaterhouseCoopers LLP, independent accountants, to audit the books, records
and accounts of the Company for the current fiscal year ending December 31,
2002. PricewaterhouseCoopers LLP has audited the Company's financial statements
since the fiscal year ended December 31, 1993.

Audit Fees

     The aggregate fees billed for professional services rendered for the audit
of the Company's annual financial statements for the fiscal year ended December
31, 2001, and for the reviews of the financial statements included in the
Company's Quarterly Reports on Form 10-Q for that fiscal year, were
approximately $190,000.

Financial Information Systems Design and Implementation Fees

     PricewaterhouseCoopers LLP did not render to the Company any professional
services relating to financial information systems design and implementation for
the fiscal year ended December 31, 2001.

All Other Fees

     The aggregate fees billed by PricewaterhouseCoopers LLP for services
rendered to the Company, other than the services described above under "Audit
Fees" for the fiscal year ended December 31, 2001, were approximately $201,000
for tax compliance and tax consulting, $101,000 for statutory audits for various
international locations and $10,000 for other services.

Vote Required

     The affirmative vote of the holders of a majority of the Company's Common
Stock represented and voting at the meeting will be required to approve and
ratify the Board's selection of PricewaterhouseCoopers LLP. With respect to such
matter, an abstention from voting will have the same affect as a vote against
the proposal. Broker non-votes do not count as votes for or against the proposal
and are not considered in calculating the number of votes necessary for
approval.

     The Board of Directors recommends a vote "FOR" the approval and
ratification of PricewaterhouseCoopers LLP as the Company's independent auditors
for 2002. In the event of a negative vote on such ratification, the Board of
Directors will reconsider its selection.

     A representative of PricewaterhouseCoopers LLP is expected to be available
at the Annual Meeting to make a statement if such representative desires to do
so and to respond to appropriate questions.

     In making its recommendation to ratify the appointment of
PricewaterhouseCoopers LLP as the Company's independent accountants for the
fiscal year ending December 31, 2002, the Audit Committee has considered whether
the non-audit services provided by PricewaterhouseCoopers LLP are compatible
with maintaining any independence of PricewaterhouseCoopers LLP.

                                       15



                                  OTHER MATTERS

    The Company knows of no other matters to be submitted to the meeting. If any
other matters properly come before the meeting, it is the intention of the
persons named in the enclosed proxy card to vote the shares they represent as
the Board of Directors may recommend.

                                              BY ORDER OF THE BOARD OF DIRECTORS

               customs and duties; review of intercompany agreements; and
               assistance with international manufacturing tax issues. Services
               of the independent accountants, excluding the financial audit and
               statutory audits, shall not exceed in the aggregate $150,000 per
               year without approval of the Committee. Under special

               illegality, errors, and irregularities are detected and
               appropriately corrected;

          7.   Review the internal audit charter and function of NI including
