CALCulate Subsystem
6.94 Operating Manual 1302.6163.12 - 03
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...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...3> attached to RESult.
The required result is selected via the following parameters:
Parameter: 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
Characteristics: *RST value: --
SCPI: device-specific
Mode: A
CALCulate<1|2>:STATistics:X:MPOSition 0 … 100
This command defines the relative X position of the mean power value for the CCDF measurement.
The default position is 0% (left corner of the grid). This function is only available if the statistics
measurement function CCDF is switched on.
Example: "CALC:STAT:X:MPOS 10.0"
' set the mean power position to 10%
Characteristics: *RST value: 0
SCPI: device-specific
Mode: A
