3 VMA Mode
3.5 Channel Power Measurement
Example
:CHP:IF:GAIN:AUTO ON
:CHP:IF:GAIN:AUTO?
Couplings Auto sets IF Gain to High Gain if the input attenuator is set to 0 dB, or if the preamp is turned on and the
frequency range is under 3.6 GHz
For other conditions, Auto sets IF Gain to Low Gain
Preset
OFF
Spur Avoidance
Because 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 instrument 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 in the
multiple capture case.
You can disable this function to speed up your measurement by setting Spur
Avoidance to Disabled (OFF).
Note that when Spur Avoidance is not in effect, either because you have disabled it
or because you are not in multiple capture, the following warning message will
appear in the status bar:
Settings Alert;Spur Avoidance Off
This is to alert you that measurement accuracy might be negatively impacted.
