OPERATION

 

 

65 

 

ANALYZE MODE 

Analyze Mode changes the operation of the OSCOR from a sweep function to a single frequency signal 
analysis.  The resolution bandwidth in Analyze Mode varies depending on the zoom level; it improves as 
you narrow the span.  Analyze Mode will demodulate an analog AM, FM, or video signal. 

To enter Analyze Mode: 

1.

 

Move the cursor to the frequency of interest (see page 33.) 

2.

 

Press the 

SWEEP/ANALYZE 

button.   

3.

 

The OSCOR unit will enter Analyze Mode. 

Note:  Analyze Mode can also be entered by using the 

Analyze 

icon found in Sweep Mode’s 

Signals

 | 

Signals

 menu. 

 

Analyze Mode Screen Elements 

•

 

Spectral Graph

 – displays a portion of the frequency spectrum, centered on the frequency 

where the cursor was located before entering Analyze Mode.   

•

 

Oscilloscope

 – an oscilloscope view of the demodulated signal.  If video demodulation is not 

turned on, the oscilloscope will be positioned just below the spectral graph and will span the 
entire width of the display.
