CALCulate<1|2>:MARKer<1 to 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, as are typical for the slots of a GSM signal, for example. 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.

TRACE 1 of the selected screen is always used by the function. The suffix of MARKer will be
ignored.
Example: "DISP:WIND:TRAC:Y:RLEV –10dBm" 'Sets the reference level to 10 dB
"INP:ATT 30 dB" 'Sets the input attenuation to 30 dB
"FREQ:CENT 935.2MHz;SPAN 0Hz" 'Sets the receive frequency to 935.2 MHz
'and the span to 0 Hz
"BAND:RES 1MHz;VID 3MHz" 'Sets the resolution bandwidth to 1 MHz
'and the video bandwidth to 3 MHz
"DET RMS" 'Sets the RMS detector
"TRIG:SOUR VID;LEV:VID 50 PCT" 'Selects the trigger source VIDeo and sets
the level of the video trigger source to
50 PCT
"SWE:TIME 50ms" 'Sets the sweep time to 50 ms
"INIT;*WAI" 'Starts the measurement with
'synchronization
"CALC:MARK:FUNC:MSUM? 50US,450US,576.9US,8"
'Queries 8 bursts with an offset of 50 µs, a
'test time of 450 µs and a period of 576.9 µs
