5.5.2 8520C Signal Selector Test Procedure
NOTE: These tests build successively on the first test in this section. Any settings not
mentioned must be left as they were in the previous test.
5.5.2.1

5.5.2.3
Amplitude, Frequency, and Phase Accuracy Test
This test uses a signal generator to input a signal with an exact amplitude, frequency, and phase
relationship through the 8520C, to the 8500C/C+. This input is also connected to the signal input of the
spectrum analyzer so that the signal level can be verified with the spectrum analyzer. The output
measurements are then compared to specifications.
