Measuring Multiple Signals
Comparing Signals on the Same Screen Using
Marker Delta
Using the analyzer, you can easily compare frequency and amplitude
differences between signals, such as radio or television signal spectra.
The analyzer delta marker function lets you compare two signals when
both appear on the screen at one time.
In this procedure, the analyzer 10 MHz signal is used to measure
frequency and amplitude differences between two signals on the same
screen. Delta marker is used to demonstrate this comparison.
Figure 2-1 An Example of Comparing Signals on the Same Screen
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.
Step 3. Set the analyzer center frequency, span and reference level to view the
10 MHz signal and its harmonics up to 50 MHz:
Press
FREQUENCY Channel, Center Freq, 30, MHz.
Press
SPAN X Scale, Span, 50, MHz.
Press
AMPLITUDE Y Scale, Ref Level, 10, dBm.
