SENSe<ch>[:POWer]:FILTer:TYPE
<Type>
The command selects the filter mode. The filter length is the multiplier for the time window
and thus directly influences the measurement time.
Parameters:
<Type>
AUTO | USER | NSRatio
AUTO
The filter length is automatically selected depending on the mea-
sured value. For high values, a short filter length is selected and
for low values a long filter length is selected.
USER
The filter length is set manually. As the filter length works as a
multiplier for the measurement time, this results in a constant
measurement time.
NSRatio
The filter lenghth (averaging factor) is selected so that the sensor's
intrinsic noise (2 standard deviations) does not exceed the speci-
fied noise content. The desired noise content is entered with com-
mand
SENSe:FILTer:NSRatio
.
To avoid very long settling times when the power is low, the aver-
aging factor can be limited with the Timeout parameter (command
SENSe:FILTer:NSRatio:MTIMe
).
*RST:
AUTO
Example:
SENS:FILT:TYPE AUTO
selects automatic filter selection.
SENSe<ch>[:POWer]:FREQuency
<Frequency>
The command sets the RF frequency of the source if the user source is selected
(
SENSe[:POWer]:SOURce USER
).
Parameters:
<Frequency>
float
*RST:
1 GHz
Example:
SENS:SOUR USER
selects user-defined source.
SENS:FREQ 2.44 GHz
enters the RF frequency of the source which is 2.44 GHz.
SENSe<ch>[:POWer]:OFFSet
<Offset>
The command enters a level offset which is added to the measured level value after
activation with command
SENSe[:POWer]:OFFSet:STATe ON
. This allows e.g. an
attenuator in the signal path to be taken into account.
