This subsystem controls the linearity deviation calculation.
Command tree: CALCulate<Chn>:LDEViation
:AUTO
:CONSTant
:ELENgth
:MODE
:SLOPe
Initiates a (re-)calculation of the linearity deviation correction factors and applies them to the active trace.
<Chn>
Channel number used to identify the active trace. If unspecified the numeric suffix is set to 1.
ONCE
Initiates the calculation
*RST value

SCPI, Command Types
Device-specific, no query.
Example:
*RST; CALC:FORM PHAS
Reset the analyzer; assign the phase of the transmission parameter S21 to the default trace.
CALC:LDEV:AUTO ONCE
Calculate correction factors and apply them to the default trace.
CALC:LDEV:SLOP?; ELEN?; CONS?
Query the values of the correction factors.
CALC:LDEV:MODE OFF
Disable the correction.
Defines the constant value for the linearity deviation calculation.
Channel number used to identify the active trace.
<Constant>
Constant value
Range [def. unit]
The range depends on the trace format. For the default trace:
–200 dB to + 200 dB [dB]. The increment (UP, DOWN) is 10-2 dB.
0 dB
Device-specific, command or query.
See CALCulate<Chn>:LDEViation:AUTO
Defines the electrical length for the linearity deviation calculation. This command is available if the active trace format is Phase or Unwrapped Phase, or if a mixer delay is measured.
<El Length>
Electrical length
0 m to + 1000 m [m]. The increment (UP, DOWN) is 10-4 m.
0 m
Applies /discards the correction factors or re-calculates them for each trace (Tracking).
ON
Apply the correction using the latest correction factors.
OFF
Discard the correction.
TRACking
Repeat calculation for each measured trace and apply the correction.
0 dB/MHz
Defines the slope of the regression line for the linearity deviation calculation.
<Slope>
Slope of the regression line
–1015 dB/MHz to +1015 dB/MHz [dB/MHz]. The increment (UP, DOWN) is 10-4 dB/MHz.
