[SENSe:]FILTer:LPASs[:STATe] <State>
This command turns a low pass filter for measurements on small carrier frequencies on
and off.
Effects of using thelow pass filter:
●
Auto search feature is turned off ([SENSe:]ADJust:CONFigure:FREQuency:
AUTosearch[:STATe]).
●
Signal count is turned off ([SENSe:]ADJust:CONFigure:FREQuency:COUNt).
●
The stop offset is limited to 30 % of the filter cut-off frequency ([SENSe:
]FREQuency:STOP).
●
DC coupling should be used for measurements on carrier frequencies below
1 MHz (INPut<ip>:COUPling).
Parameters:
<State> ON | OFF | 1 | 0
When you turn on the filter, you can define a cutoff frequency
with [SENSe:]FILTer:LPASs:FREQuency:MANual.
