CALCulate<1|2>:MARKer<1...4>:FUNCtion:SUMMary:REFerence:AUTO ONCE
With this command the currently measured average value (...:SUMMary:MEAN) and RMS value (...:
SUMMary:RMS)are declared as reference values for relative measurements in the indicated
measurement window. The function is independent of the marker selection, i.e. the numeric suffix
<1 to 4> of :MARKer is irrelevant. It is only available in the time domain (span = 0).
If the measurement of RMS value and average is not activated, the reference value 0 dBm is used.
If the function ...:SUMMary:AVERage or ...:SUMMary:PHOLd is switched on, the current value is the
accumulated measurement value at the time considered.
Example:
"CALC:MARK:FUNC:SUMM:REF:AUTO ONCE"
'Takes the currently measured power in screen A as reference value for the relative
time domain power measurement.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A-T
This command is an event and therefore has no *RST value and no query.
CALCulate<1|2>:MARKer<1...4>:FUNCtion:SUMMary:AOFF
This command switches off all time domain measurements in the selected measurement window. The
function is independent of the marker selection, i.e. the numeric suffix <1...4> of :MARKer is irrelevant.
It is only available in the time domain (span = 0).
Example:
"CALC2:MARK:FUNC:SUMM:AOFF"
'Switches off the time domain power measurement functions in screen B.
Characteristics: *RST value: _
SCPI: device-specific
Mode: A-T
This command is an event and therefore has no *RST value and no query.
CALCulate<1|2>:MARKer<1...4>:FUNCtion:MSUMmary? <time offset of first pulse>, <measurement
time>, <period>, < # of pulses to measure>
The commands of this subsystem are used to determine the power of a sequence of signal pulses
having the same interval. The number of pulses to be measured as well as the measurement time and
the period can be set. To define the position of the first pulse in the trace, a suitable offset can be
entered.
The evaluation is performed on the measurement data of a previously recorded trace. The data
recorded during the set measurement time is combined to a measured value for each pulse according
to the detector specified and the indicated number of results is output as a list.
