Af Analyzer Distortion And Sinad Accuracy; Performance Test 14 - Agilent Technologies E8285A Manual

AF Analyzer Distortion and SINAD Accuracy

Performance Test 14

The purpose of this test is to verify that the Test Set meets the specification limits
in PTR (Performance Test Record)
SINAD Accuracy Test 14 Record" on page
created by summing the two internal audio generators. Levels are measured
separately by the internal AC voltmeter. One source is set to a harmonic two or
three times the frequency of the other. The measured distortion and SINAD is
compared with the calculated value.
