The list evaluation is incompatible to other measurement functions (e.g. marker func-
tionality or statistics). If you use a command that controls those functions, the
R&S
FPL1000 aborts the list evaluation.
The R&S FPL1000 also aborts the list evaluation if you end the remote session.
The commands can be used in two different ways.
●
Instrument setup, measurement and querying of the results in a single command
line. This method causes the least delay between the measurement and the result
output. However, it requires the control computer to wait for the response from the
instrument.
●
Instrument setup and querying of the result list at the end of the measurement:
With this method, the control computer may be used for other activities while the
measurement is being performed. However, more time is needed for synchroniza-
tion via service request.
8.6.12.1 Performing List Evaluations
All remote control commands specific to list evaluations (which are available via
remote control only) are described here.
Remote commands exclusive to list evaluation
[SENSe:]LIST:POWer:RESult?

[SENSe:]LIST:POWer[:SEQuence]

[SENSe:]LIST:POWer:SET
............................................................................................. 623
[SENSe:]LIST:POWer:STATe
..........................................................................................623
[SENSe:]LIST:POWer:RESult?
This command queries the results of the list evaluation.
This command may be used to obtain measurement results in an asynchronous way,
using the service request mechanism for synchronization to the end of the measure-
ment.
If there are no results, the command returns an error.
Return values:
<PowerLevel> Power level for each frequency included in the measurement.
The command returns up to 3 power levels for each frequency,
depending on the number of evaluation modes you have turned
on with
[SENSe:]LIST:POWer:SET
.
The result is a list of floating point values separated by commas.
The unit depends on
CALCulate<n>:UNIT:POWer
.
Usage: Query only
