Remote Control – Description of Commands
SENSe Subsystem
For allowed <rbw> setting for <filter type> = CFILter and <filter type> = RRC see section
Bandwidths and Sweep Time – BW Key”
“List of Available Channel Filters” on page 4.118
Return value:
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
Example:
<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, in 1, 2, 3, 5, 10 steps for <filter type>
= NORMal.
See filter table for <filter type> = CFILter and <filter
type> = RRC. For possible combinations of filter type
and filter bandwidth see table "List of available
channel filters" in chapter
,
“Setting the Bandwidths and Sweep Time –
.
<vbw>:
Video bandwidth
Range of values:
1 Hz to 10 MHz in 1, 2, 3, 5, 10 steps.
The value is ignored for <filter type> = CFILter or RRC
<meas time>:
Measurement time
Range of values:
1us to 30s
<trigger level>:
Reserved. Must be set to 0.
