FSE CALCulate Subsystem
1065.6016.12 6.19 E-16
CALCulate:FORMat and CALCulate:FSK Subsystems
The CALCulate:FORMat and CALCulate:FSK subsystems determine further processing and conversion
of measured data in operating mode vector signal analysis.
This sub system is only valid in connection with option FSE-B7, Vector Signal Analysis.

This command defines the display of the traces.
Example: ":CALC:FORM CONS"
Features: *RST value: MAGNitude
SCPI: conforming
Mode: VA-D
The availability of the parameters depends on the selected data (see command
:CALCulate:FEED).
Available for selection measurement signal, reference signal and modulation error
(CALCulate:FEED ‘XTIM:DDEM:MEAS’,‘XTIM:DDEM:REF) ,‘XTIM:DDEM:ERR:MPH’):
MAGNitude Display of the magnitude in the time domain (only available for settings
:CALCulate:FEED ‘XTIM:DDEM:ERR:MPH’ (error signal) or
‘XTIM:DDEM:MEAS’ (measurement signal) or ‘XTIM:DDEM:REF’
(reference signal)
PHASe | UPHase Display of the phase in the time domain with or without (”unwrapped”)
limitation to ±180°
RIMag Display of the time characteristic of inphase and quadrature
component
FREQuency Display of the frequency response in the time domain
COMP Display of the polar vector diagram (complex)
CONS Display of the polar vector diagaram (constellation)
Available for selection measurement signal and reference signal (CALCulate:FEED
‘XTIM:DDEM:MEAS’,‘XTIM:DDEM:REF):
IEYE | QEYE Eye diagram of the inphase or quadrature component
TEYE Display of the trellis diagram
FEYE Eye diagram of FSK modulation
:CALCulate<1|2>:FSK:DEViation:REFerence <numeric_value>
This command defines the reference value of the frequency deviation for FSK modulation.
Example: ":CALC:FSK:DEV:REF 20kHz"
Features: *RST value: -
SCPI: device-specific
Mode: VA-D
