[SENSe:]LIST:POWer[:SEQuence]
This command configures and initiates the List Evaluation measurement.
The list can contain up to 200 entries (frequencies). You can define a different instru-
ment setup for each frequency that is in the list.
If you synchronize the measurement with
*OPC
, the R&S FPL1000 produces a service
request when all frequencies have been measured and the number of individual mea-
surements has been performed.
Note that using the command as a query initiates the measurement and returns the
results if all frequencies have been measured. For more information on querying the
results see
[SENSe:]LIST:POWer:RESult?
.
Parameters:
<Frequency> Defines the frequency. Each frequency corresponds to one list
entry.
Range:
0 to Fmax

<RefLevel> Defines the reference level for a list entry.
Range:
-130 to 30

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
.
