SET-UP & BASIC OPERATION
11
Press
SWEEP/ANALYZE
to
enter Analyze mode. Press
Mute or Vol Up to listen to
the radio station.
To listen to other known
signals, type in the desired
frequency or use the rotary
knob to move the cursor to
adjacent stations.
When you first enter Analyze Mode, the spectral graph will appear in the top portion of the screen, just
like Sweep Mode. An oscilloscope view of the demodulated signal will appear in the bottom portion of
the screen. Also, by default three traces are displayed in the spectral graph in Analyze Mode: the real
time trace, the peak trace, and an average trace.
Using the techniques of this exercise you should be able to quickly go to any signal for spectrum analysis
and analog demodulation. To practice, it is recommended that you look at several different signals
throughout the frequency spectrum such as pager transmissions, television signals, cellular phone
signals, etc… Options for Video Demodulation can be found within the Demod Sub-Menu, just select the
Video
icon. Options for subcarrier demodulation can be found within the Subcarrier Sub-Menu.
