Operating instructions

R&S ESCI SENSe:LIST Subsystem
1166.6004.12 6.173 E-1
OFF: always OFF
<filter type>: NORMal: normal resolution filter
CFILter: channel filter. These are especially steep-edged
filters, which are used for example in Fast ACP
measurement to ensure the band-limiting of a
transmission channel in the time domain.
RRC: Root Raised Cosine filter. This special filter form
is used to determine the channel power for some
mobile radio standards.
<rbw>: Resolution bandwidth
Range of values: 10 Hz to 10 MHz, 50 MHz
in 1, 3, 10 steps for
<filter type> = NORMal.
See filter table for <filter type> = CFILter
and <filter type> = RRC.
Possible combinations
of filter type and
filter bandwidth
see table "List of
available channel filters"
in section "Setting
Bandwidths and Sweep
Time – Key BW".
<vbw>: Video bandwidth
Range of values: 1 Hz to 10 MHz in 1, 3, 10 steps.
<meas time>: Measurement time
Range of values: 1us to 30s
<trigger level>: Reserved. Must be set to 0.
Returned values:
The query command returns a list of comma-separated values (CSV) which contains the power
measurement results in floating-point format. The unit depends on the setting with CALC:UNIT.
Command
"SENSe:LIST:POWer? 935.2MHz,-20dBm,10dB,OFF,NORM,1MHz,3MHz,434us,0,
935.4MHz,-20dBm,10dB,OFF,NORM,30kHz,100kHz,434us,0,
935.6MHz,-20dBm,10dB,OFF,NORM,30kHz,100kHz,434us,0"
thus returns the following list, for example:
-28.3,-30.6,-38.1
If the command sequence is extended to
"SENSe:LIST:POWer:SET ON,ON,ON,IMM,POS,0,0"
"SENSe:LIST:POWer? 935.2MHz,-20dBm,10dB,OFF,NORM,1MHz,3MHz,434us,0,
935.4MHz,-20dBm,10dB,OFF,NORM,30kHz,100kHz,434us,0,
935.6MHz,-20dBm,10dB,OFF,NORM,30kHz,100kHz,434us,0"
the result list is extended to 3 results per frequency point (peak, RMS and average):
-28.3, -29.6, 1.5, -30.6, -31.9, 0.9, -38.1, -40.0, 2.3
Examples:
"SENSe:LIST:POWer 935.2MHz,-20dBm,10dB,OFF,NORM,1MHz,3MHz,434us,0,
935.4MHz,-20dBm,10dB,OFF,CFIL,30kHz,100kHz,434us,0,
935.6MHz,-20dBm,10dB,OFF,CFIL,30kHz,100kHz,434us,0"
performs a measurement sequence with the following settings:
