X-AXIS
RANGE
The X-AXIS RANGE softkey changes the level range to be
covered by the statistics measurement selected.
The function is identical to softkey
RANGE LOG MANUAL in
menu
AMPT.
IEC/IEEE command:
CALC:STAT:SCAL:X:RANG <value>
Y-AXIS
MAX VALUE
The Y-AXIS MAX VALUE softkey defines the upper limit of the
displayed probability range.
Values on the y-axis are normalized which means that the
maximum value is 1.0. As the y-axis scaling has a logarithmic axis
the distance between max and min value must be at least one
decade.
IEC/IEEE command:
CALC:STAT:SCAL:Y:UPP <value>
Y-AXIS
MIN VALUE
The Y-AXIS MIN VALUE softkey defines the lower limit of the
displayed probability range.
As the y-axis scaling has a logarithmic axis the distance between
max and min value must be at least one decade. Valid values are
in the range 0 < value < 1.
IEC/IEEE command:
CALC:STAT:SCAL:Y:LOW <value>
ADJUST
SETTINGS
see below
DEFAULT
SETTINGS
The DEFAULT SETTINGS softkey resets the x- and y-axis
scalings to their PRESET values.
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
IEC/IEEE-bus command:
CALC:STAT:PRES
ADJUST
SETTINGS
The ADJUST SETTINGS softkey optimizes the level settings of the R&S
ESCI according to the measured peak power in order to gain maximum
sensitivity of the instrument.
The level range is adjusted according to the measured difference between
peak and minimum power for APD measurement and peak and mean power
for CCDF measurement in order to obtain maximum power resolution.
Additionally the probability scale is adapted to the selected number of
samples.
IEC/IEEE-bus command:
CALC:STAT:SCAL:AUTO ONCE
