Chapter 2 Performance Tests

Introduction

Introduction

This chapter provides procedures to test the electrical performance of the 58502A Distribution Amplifier specifications listed in Chapter 7, “This chapter provides electrical specifications and supplemental characteristics for the 58502A Broadband Distribution Amplifier. Electrical specifications describe the instrument’s warranted performance. Supplemental characteristics are intended to provide information useful to apply to the instrument by giving typical or nominal, but non-warranted performance parameters.,” of this guide. It also provides calibration procedures for the 58502A units that contain the Option 010 Backup Oscillator.

Three types of testing are provided:

Operational Verification, starting on page 2-2

Performance Tests, starting on page 2-2

Calibration (Option 010 Only), starting on page 2-2

Operational Verification

The Operational Verification test is an abbreviated series of checks that may be performed to give a high degree of confidence that the instrument is operating properly without performing the Acceptance Test. An operational verification is useful for incoming inspection and after instrument repair.

Performance Tests

The Performance Tests verify the specifications listed in Chapter 7, “Specifications.” All tests can be performed without access to the inside of the instrument.

Calibration (Option 010 Only)

The recommended 58502A calibration period is 12 months. You may perform calibration more often to obtain greater accuracy. This is dependent on the aging rate of the 58502A’s internal reference oscillator and the amount of deviation from the frequency stability needed for your application.

Test Record

The results of the Operational Verification, and Acceptance Test should be recorded on a copy of the Acceptance Test Record, located at the end of this chapter.
