ALCulate:STATistics:RESult<1...6>?
This command reads out the results of statistical measurements of a recorded trace. The trace
is selected with the numeric suffix <1...6> attached to RESult.
Parameter
The required result is selected via the following parameters:
MEAN Average (=RMS) power in dBm measured during the measurement time.
PEAK Peak power in dBm measured during the measurement time.
CFACtor Determined CREST factor (= ratio of peak power to average power) in dB.
ALL Results of all three measurements mentioned before, separated by commas:
<mean po
wer>,<peak po
wer>,<crest f
actor>
Example
CALC:STAT:RES2? ALL
Reads out the three measurement results of trace 2. Example of answer string:
5.56,19.25,13.69 i.e. mean power: 5.56 dBm, peak power 19.25 dBm, CREST factor 13.69 dB
Characteristics
*RST value: –
SCPI: device–specific
Mode
A, CATV, CDMA, EVDO
CALCulate:STATistics:SCALe:AUTO
This command optimizes the level setting of the instrument depending on the measured peak
power, in order to obtain maximum instrument sensitivity.
To obtain maximum resolution, the level range is set as a function of the measured spacing
between peak power and the minimum power for the APD measurement and of the spacing
between peak power and mean power for the CCDF measurement. In addition, the probability
scale for the number of test points is adapted.
This command is an event and therefore has no *RST value and no query.
Note: Subsequent commands have to be synchronized with *WAI, *OPC or *OPC? to the end
of the auto range process which would otherwise be aborted.
Parameter
ONCE
Example
CALC:STAT:SCAL:AUTO ONCE;*WAI
Adapts the level setting for statistical measurements.
Characteristics
*RST value: –
SCPI: device–specific
Mode
