Return values:
<List> string list
*RST:
0
Usage: Query only
Manual operation: See " S-Parameter " on page 73
:SENSe<ch>[:POWer]:FILTer:LENGth:AUTO?
Queries the current filter length in filter mode
AUTO
(
:SENSe<ch>[:POWer]:
FILTer:TYPE
)
Return values:
<Auto> float
Range:
1 to 65536
Example: SENS1:FILT:TYPE AUTO
Selects auto filter.
SENS1:FILT:LENG:AUTO?
Queries the automatically set filter length.
Response: 1024
Usage: Query only
Manual operation: See "Filter Length" on page 72
:SENSe<ch>[:POWer]:FILTer:LENGth[:USER] <User>
Selects the filter length for
SENS:POW:FILT:TYPE USER
. As the filter length works as
a multiplier for the time window, a constant filter length results in a constant measure-
ment time (see also
"About the measuring principle, averaging filter, filter length, and
achieving stable results" on page 66).
The R&S NRP power sensors provide different resolutions for setting the filter length,
depending on the used sensor type:
●
Resolution = 1 for R&S NRPxx power sensors
●
Resolution = 2 n for sensors of the R&S NRP-Zxx family, with n = 1 to 16
Parameters:
<User> float
Range:
1 to 65536
*RST: 1
Example: SENS1:FILT:TYPE USER
Selects user filter mode.
SENS1:FILT:LENG 16
Sets a filter length of 16. E.g. using a sensor with 20 ms time
window, the resulting measurement time is 640 ms (2x16x20
ms)
