5071A Complete Performance Tests
Before performing the following tests, the 5071A under test must have been in
operation for at least 30 minutes. If you are initially starting the 5071A, follow
the instructions in the subsection ―Power-On Self-Tests and Servo Lock‖ on page
140 of the Operational Verification section in this appendix.
Test 1 Output Signals: Harmonic Distortion and Spurious Signals
Check
A. Harmonic Distortion Check for the 5 and 10 MHz Outputs
Harmonics on the 10 MHz and 5 MHz output signals must be more than 40 dBc
below the fundamental. To perform this check, a spectrum analyzer is tuned to
the fundamental frequency and an amplitude reference is established. The output
frequency spectrum is then examined to determine fundamental-to-sideband
amplitude relationship at harmonic points of the fundamental.
Equipment
HP/Agilent 3585B Spectrum Analyzer
Setup

Specifications
Verify all harmonics are < -40 dBc with respect to the fundamental frequency.
