[:SENSe]:PVTime:IF:GAIN[:STATe] ON | OFF | 1 | 0
[:SENSe]:PVTime:IF:GAIN[:STATe]?
Example
:PVT:IF:GAIN OFF
:PVT:IF:GAIN?
Notes Where ON = high gain
OFF = low gain
This only applies to the RF input. It does not apply to baseband I/Q input
Dependencies This control does not appear in UXM
Couplings When either the auto attenuation works (for example, with the electrical attenuator) or optimize
mechanical attenuator range is requested, the IF Gain setting is changed according to the following
rule
‘Auto’ sets IF Gain to ‘High Gain’ under any of the following conditions: the input attenuator is set to 0
dB, the preamp is turned on, or the Max Mixer Level is −20 dBm or lower. For other settings, ‘Auto”
sets IF Gain to ‘Low Gain’
Preset OFF
State Saved Yes
Range Low Gain | High Gain
Spur Avoidance
Because the VXT models M9410A/11A/15A are direct-conversion (zero-IF)
receivers, feedthrough leakage from the local oscillator appears as a spurious signal
(spur) at the center frequency. The Spur Avoidance function is provided to eliminate
this spur, at the expense of some measurement speed.
When Spur Avoidance is enabled (the default), the analyzer uses a software
algorithm to remove this spur from the displayed measurement data, but the
algorithm only operates under certain conditions. Specifically, it only operates when
the BW<= maxBW/2.5, see More Information.
You can disable this function in order to speed up your measurement. When Spur
Avoidance is turned Off, a warning message will appear in the status bar as
“Settings Alert;Spur Avoidance Off”. This is to alert you that measurement accuracy
might be impacted because you have defeated the spur avoidance algorithm.
