g. Press START key.
h. Verify that no signal aliasing remains on display above 0.005 IPS.

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

Test Setup

Connect equipment as shown in Figure 5-9.
5.5.2.2

Power-Up Self-Test

a. Hold down START key on 8500C/C+ and turn on power supply.
b. Wait until Power-Up Self-Test display appears and release START key.
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.
