R&S FSL Power Measurements – MEAS Key
1300.2519.12 4.103 E-11
x–Axis Ref Level
Opens an edit dialog box to enter the reference level in the currently active unit (dBm, dBMV,
etc). The function of this softkey is identical to the Ref Level softkey in the amplitude menu.
For the APD function this value is mapped to the right diagram border. For the CCDF function
there is no direct representation of this value on the diagram as the x–axis is scaled relatively to
the measured mean power.
Remote: CALC:STAT:SCAL:X:RLEV <value>
x–Axis Range
Opens the Range Log dialog box to select a value for the level range to be covered by the
statistics measurement selected. The function is identical to the Range Log softkey in amplitude
menu.
Remote: CALC:STAT:SCAL:X:RANG <value>
y–Axis Max Value
Opens an edit dialog box to define the upper limit of the displayed probability range. Values on
the y–axis are normalized which means that the maximum value is 1.0. The y–axis scaling is
defined via the y–Unit %/Abs softkey. If the y–axis has logarithmic scale, the distance between
max and min value must be at least one decade.
Remote: CALC:STAT:SCAL:Y:UPP <value>
y–Axis Min Value
Opens an edit dialog box to define the lower limit of the displayed probability range. Values in
the range 0 < value < 1 are allowed. The y–axis scaling is defined via the y–Unit %/Abs softkey.
If the y–axis has logarithmic scale, the distance between max and min value must be at least
one decade.
Remote: CALC:STAT:SCAL:Y:LOW <value>
y–Unit %/Abs
Defines the scaling type of the y–axis. The default value is absolute scaling.
This softkey is available from firmware version 1.80.
Remote: CALC:STAT:SCAL:Y:UNIT PCT
