Measuring Multiple Signals
Comparing Signals not on the Same Screen
Using Marker Delta
Measure the frequency and amplitude difference between two signals
that do not appear on the screen at one time. (This technique is useful
for harmonic distortion tests when narrow span and narrow bandwidth
are necessary to measure the low level harmonics.)
In this procedure, the analyzer 10 MHz signal is used to measure
frequency and amplitude differences between one signal on screen and
one signal off screen. Delta marker is used to demonstrate this
comparison.

Step 1. Preset the analyzer:
Press
Preset, Factory Preset (if present).
Step 2. (PSA)
a. Enable the rear panel 10 MHz output:
Press
System, Reference, 10 MHz Out (On).
b. Connect the 10 MHz OUT (SWITCHED) from the rear panel to the front
panel RF input:
(ESA)
Connect the rear panel 10 MHz REF OUT to the front panel RF input.
