CALCulate:STATistics:SCALe:Y:LOWer 1E-9 to 0.1
This command defines the lower limit for th Y axis of the diagram in statistical measurements. Since
probabilities are specified on the Y axis, the entered numerical values are dimensionless.
Example: "CALC:STAT:SCAL:Y:LOW 0.001"
Characteristics: *RST value: 1E-6
SCPI: device-specific
Mode: A
CALCulate:STATistics:PRESet
This command resets the scaling of the X and Y axes in a statistical measurement. The following
values are set:
X axis ref level: -20 dBm
X axis range APD: 100 dB
X axis range CCDF: 20 dB
Y axis upper limit: 1.0
Y axis lower limit: 1E-6
Example: "CALC:STAT:PRES" 'Resets the scaling for statistical functions
Characteristics: *RST value: --
SCPI: device-specific
Mode: A
This command is an event and therefore has no *RST value and no query.
CALCulate:STATistics:RESult<1 to 3>? MEAN | PEAK | CFACtor | ALL
This command reads out the results of statistical measurements of a recorded trace. The trace is
selected with the numeric suffix <1 to 3> 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 power>,<peak power>,<crest factor>
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
