R&S FSMR CALCulate:STATistics Subsystem
1313.9723.12 6.1-87 E-1
CALCulate:STATistics:CCDF:X<1 to 3>? P0_1 | P1 | P10
This command reads out the level values for the probabilities 0.1%, 1% and 10%. The trace is
selected by means of the numeric suffix <1 to 3>.
Parameters: The desired result is selected by means of the following parameters:
P0_1 Level value for 0.1% probability
P1 Level value for 1% probability
P10 Level value for 10% probability
Example: "
CALC:STAT:CCDF:X? P1"
'Reads out the level values for 1% probability.
Characteristics: *RST value: --
SCPI: device-specific
CALCulate:STATistics:NSAMples 100 to 1E9
This command sets the number of measurement points to be acquired for the statistical
measurement functions.
Example: "
CALC:STAT:NSAM 500"
'Sets the number of measurement points to be
'acquired to 500.
Characteristics: *RST value: 100000
SCPI: device-specific
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
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.
