Programming The CALL CONFIGURE Screen
Detector
This field is used to select the type of detector used to measure the amplitude of
the audio signal being analyzed on the ANALOG MEAS screen. The Detector
field is imported from the AF ANALYZER screen and is programmed exactly as it
is on its home screen. See "AF Analyzer" on page 91 for programming command
syntax.
Input Att
The Input Att field sets the amount of input attenuation for signals entering the RF
IN/OUT and ANT IN connectors. The Input Att field displays the present
attenuation value, and when selected, is used to set the desired attenuation level.
The :CRFAttenuator command is used to control this field.
The query form (that is, :CRFAttenuator?) can be used to query the current field
value.
Syntax
:CRFAttenuator <‘><0 dB/20 dB/40 dB><’>
:CRFAttenuator?
Example
OUTPUT 714;"CALLP:AMPS:CRFA ‘40 dB’"
OUTPUT 714;"CALLP:AMPS:CRFA?"
ENTER 714;Attenuator_set$
Operating Considerations
This is a priority control field. Accessing the CALL CONFIGURE screen
overrides any changes made to this field in other screens. The other screens
affected include the RF ANALYZER screen and the SPECTRUM ANALYZER
screen.
