Comparing Signals on the Same Screen Using Marker Delta

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.

Step
1 Connect the 10 MHz OUT
from the rear panel to the
front panel RF input.
2 Select the mode.
3 Preset the mode.
4 Configure the analyzer
settings.
Action

Notes
This sets the analyzer center
frequency, span and reference
level to view the 10 MHz signal
and its harmonics up to 50
MHz.
