Series Spectrum Analyzers)
Step 10. Enter points 2 through 11 from Table 12-1:
Step 11. Turn the limits on:
Press
Return, Limit (On).
Step 12. Turn the limit test on to determine if the fundamental signal and
harmonics pass:
Press
Test (On).

This procedure can verify compliance with phase noise and harmonics
specifications. You can save this instrument state and limit lines in a
“setup” type file for future applications (
File, Save, Type, Setup,
Save Now). Replace the 10 MHz reference signal of the analyzer with
the device under test (DUT) to create a similar measurement.
