R&S ESU Remote Control – Description of Commands
SENSe Subsystem
6.196 Operating Manual 1302.6163.12 - 03
Characteristics: *RST value: --
SCPI: instrument-specific
Mode: A-F, A-T
[SENSe<1|2>:]MPOWer:RESult[:LIST]?
This command queries the results of a multiple burst power measurement as configured and initiated
with
SENSe:MPOWer[:SEQuence]
. The results are output in a comma-separated list of floating point
values. The unit used for the return values is always dBm.
This command may be used to obtain measurement results in an asynchronous way using the service
request mechanism for synchronization with the end of the measurement.
If no measurement results are available, the command will return a query error.
Example:
*ESE 1
*SRE 32
'Configuration of status reporting systems for the generation of an SRQ on
operation complete
SENSe:MPOWer
935.2MHz,1MHz,434us,VIDEO,50PCT,5us,MEAN,20;*OPC
'Configuring and starting the measurement
...
'Further actions of the control computer during measurement
On SRQ:
'Response to service request
SENSe:MPOWer:RESult?
Characteristics: *RST value: --
SCPI: instrument-specific
Mode: A-F, A-T
The measurement function always uses trace 1 in the selected screen, and acti-
vates the selected screen.
Repeated use of the command without changes to its parameters (i.e. using the
same settings again) will speed up the measurement since the previous hardware
settings will be cached and therefore additional hardware settling times will be
avoided. This also holds true if only part of the parameters (e.g. only the trigger
delay) are changed, as in this case the rest of the parameters will be cached.
This measurement is not compatible with other measurements, especially as far
as marker functions, adjacent channel measurement or statistics are concerned.
The corresponding functions are therefore automatically switched off. In return
incompatible commands will automatically deactivate the multi burst power func-
tion.
The function is only available in the remote control. It is deactivated on switching
back to LOCAL.
If available also the RRC and the CFILer filter type can be used by defining it with
the command ”
BAND|BWID:TYPE NORM | FFT | CFIL | RRC
“ before using
the MPOW command.
