SECTION IV

PERFORMANCE TESTS

4-1. INTRODUCTION 4-3. INSTRUMENTSTESTED

4-2.The procedures in this section test the electrical performance of the instrument using the specifications in Section I as the performance standards. The performance tests included in this section are listed in Table 4-1.Most of the tests can be performed without access to the interior of the instrument. If a test measurement is marginal, perform the appropriate adjustment procedures in Section V.

4-4. Since a compatible display mainframe is required for operation of the HP Model 8559A Spectrum Analyzer plug-in, the specifications listed in Table 1-1 apply when both instruments are functioning together. Consequently, the performance tests in this section verify the proper operation of both the HP 8559A and the display mainframe.

4-5. EQUIPMENT REQUIRED

4-6. he equipment required for the performance tests is listed under Recommended Test Equipment in Section I. Any equipment that satisfies the critical specifications given in the table may be substituted for the recommended model.

4-7. TEST RECORD

4-8. Results of the performance tests may be tabulated in the Performance Test Record at the end of this section. The test record lists test specifications and acceptable limits.

4-9. CALIBRATION CYCLE

4-10.This instrument requires periodic calibration. Calibration should be verified every six months by means of the performance tests.
