The following documents filed by the Registrant with the Commission pursuant to the Securities Exchange Act of 1934 (the "Exchange Act"), are incorporated in this Registration Statement by reference as of their respective dates (File No. 1-6462):

-3-

offered herein have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference in this Registration Statement and to be a part hereof from the date of filing of such documents.

Item 4. Description of Securities.

Not applicable.

Item 5. Interest of Named Experts and Counsel.

The validity of the Common Stock offered hereby has been passed on by Testa, Hurwitz & Thibeault, LLP, 125 High Street, Boston, Massachusetts 02110, which serves as general counsel to the Registrant. Richard J. Testa, a member of the firm and Clerk, Secretary and a director of the Registrant, owned beneficially 32,000 shares of Common Stock of the Registrant as of April 7, 1997.

Item 6. Indemnification of Directors and Officers.

Section 67 of the Massachusetts Business Corporation Law ("Section 67") provides that a corporation may indemnify its directors and officers to the extent specified in or authorized by (i) the articles of organization, (ii) a by-law adopted by the stockholders, or (iii) a vote adopted by the holders of a majority of the shares of stock entitled to vote on the election of directors. In all instances, the extent to which a corporation provides indemnification to its directors and officers under Section 67 is optional. Section 2 of Article VI of the Registrant's Amended and Restated By-laws provides that each director and officer shall be indemnified by the Registrant against liabilities and expenses in connection with any legal proceeding to which such officer or director may become a party by reason of being or having been an officer or director of the Registrant or of any organization in which the Registrant directly or indirectly owns shares or of which the Registrant is a creditor, and provides that the Board of Directors of the Registrant may, without stockholder approval, authorize the Registrant to enter into agreements, including any amendments or modifications thereto, with any of its directors or officers providing for indemnification of such person to the maximum extent permitted under applicable law and the Registrant's Restated Articles of Organization, as amended, and Amended and Restated By-Laws.

Article Six of the Registrant's Restated Articles of Organization ("Article Six") eliminates the personal liability of the Registrant's directors for monetary damages for breach of their fiduciary duty as directors to the Registrant and its stockholders, notwithstanding any provision of law imposing such liability. Article Six does not, however, eliminate liability of the Registrant's directors (i) for breach of the director's duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under
Section 61 or 62 of the Massachusetts Business Corporation Law, or (iv) for any transaction from which the director derived an improper personal benefit.

The Registrant and its directors and officers are covered by liability insurance. In addition, the directors and officers of the Registrant are covered by individual indemnification agreements with the Registrant.

Item 7. Exemption From Registration Claimed.

Not applicable.

                    (found on Page 7 of this Registration Statement)

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by
Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

-5-

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Re: Registration Statement on Form S-8 Relating to the Teradyne, Inc. 1996 Non-Employee Director Stock Option Plan (the "Plan")

Ladies and Gentlemen:

Reference is made to the above-captioned Registration Statement on Form S-8 (the "Registration Statement") filed by Teradyne, Inc. (the "Company") with the Securities and Exchange Commission under the Securities Act of 1933, as amended, relating to 800,000 shares of Common Stock, $.125 par value, of the Company (the "Shares").

We are counsel to the Company and are familiar with the proceedings of its stockholders and Board of Directors. We have examined original or certified copies of the Company's certificate of incorporation, as amended, the Company's by-laws, as amended, the corporate records of the Company to the date hereof, and such other certificates, documents, records and materials as we have deemed necessary in connection with this opinion letter.

We are members only of the Bar of the Commonwealth of Massachusetts and are not experts in, and express no opinion regarding, the laws of any jurisdiction other than the Commonwealth of Massachusetts and the United States of America, and the General Corporation Law of the State of Delaware.

Based upon and subject to the foregoing, we are of the opinion that the Shares issued or proposed to be issued by the Company pursuant to the Plan will be, upon receipt of the consideration provided for in the Plan, validly issued, fully paid and nonassessable after issuance of such Shares in accordance with the terms of the Plan.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement.

Very truly yours,

/s/ Testa, Hurwitz & Thibeault, LLP.
