R&S FSW-K7
Range
Defines the displayed y-axis range in dB.
The default value is 100 dB.
For Analog Demodulation measurements, time domain scaling is defined in Hz
(default: 500 kHz).
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]
Ref Level Position
Defines the reference level position, i.e. the position of the maximum AD converter
value on the level axis in %, where 0 % corresponds to the lower and 100 % to the
upper limit of the diagram.
Only available for RF measurements.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RPOSition
Auto Scale Once
Automatically determines the optimal range and reference level position to be dis-
played for the current measurement settings.
The display is only set once; it is not adapted further if the measurement settings are
changed again.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:AUTO ONCE
Scaling
Defines the scaling method for the y-axis.
"Logarithmic"
"Linear Unit"
"Linear Per-
cent"
"Absolute"
"Relative"
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y:SPACing
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:MODE

Access: "Overview" > "Demod Settings" > "Unit"

Logarithmic scaling (only available for logarithmic units - dB..., and A,
V, Watt)
Linear scaling in the unit of the measured signal
Linear scaling in percentages from 0 to 100
The labeling of the level lines refers to the absolute value of the refer-
ence level (not available for "Linear Percent")
The scaling is in dB, relative to the reference level (only available for
logarithmic units - dB...). The upper line of the grid (reference level) is
always at 0 dB.
