Description of command
This command defines upper limits for the 95
th
percentile of the three quantities error vector magnitude , modula-
tion error , and phase error . The 95
th
percentile is the limit below which 95% of the measured errors are located.

– V2.15
Description of command
If used as a setting command with the parameter ON this command sets all parameters of the subsystem to their
default values (the setting OFF causes an error message).
If used as a query the command returns whether all parameters are set to their default values (ON) or not (OFF) .
Measured Values – Subsystem MODulation:OVERview:EPSK
The subsystem MODulation:OVERview:EPSK measures and returns the modulation parameters and
compares them with the tolerance values. The subsystem corresponds to the various output elements
in the measurement menu
