Chapter 4, Description of Fields

Fields

Span

This field is displayed when the Controls field is set to Main. This field sets the span of frequencies to be displayed on the screen.

GPIB Example

“DISP CSP;CSP:SPAN 3 MHZ“

sets the frequency span to 3 MHz.

Operating Considerations

When the Tracking Generator is used, the span also defines the frequency sweep range.

Spans >1.5 MHz disable the AF Analyzer when the analyzer’s AF Anl In field is set to FM Demod, AM Demod, or SSB Demod. This disables all the AF Analyzer’s measurement and output functions. When the AF Analyzer’s AF Anl In field is set to any of the other available inputs, such as Audio In or Ext Mod, the speaker and AUDIO MONITOR OUTPUT are not affected when the Spectrum Analyzer’s span is changed.

The span setting is coupled to the BW= field.

Range of values: 10 kHz to 5 MHz

Screens Where Field is Present

SPECTRUM ANALYZER

CDMA REVERSE CHANNEL SPECTRUM

Speaker ALC

Speaker Automatic Level Control enables/disables the ALC function for the instrument’s internal speaker. When On is selected, the speaker volume is independent of the signal level being measured. When Off is selected, the speaker volume is dependent on the signal level being measured.
