22. (with units of dB) is the dc error offset of I/Q, from
I/Q Offset Max
the origin. This is the maximum of the individual carrier
feed-through measurements.
23.
Amplitude Droop Error Avg
best fit of the amplitude slope of the measured signal. If
averaging is on, this is the average of the individual
measurements.
24.
Amplitude Droop Error Max
best fit of the amplitude slope of the measured signal. This is the
maximum of the individual measurements.
- Returns a trace of the error vector magnitude (EVM), as
EVM Trace
comma-separated trace points in percent. The first value is the
symbol 0 decision point. The trace is interpolated for the currently
selected points/symbol displayed on the front panel. The number of
trace points depends on the current measurement interval setting.
- Returns a trace of the magnitude error, as
Mag Error Trace
comma-separated trace points in percent. The first value is the
symbol 0 decision point. The trace is interpolated for the currently
selected points/symbol displayed on the front panel. The number of
trace points depends on the current measurement interval setting.
- Returns a trace of the phase error, as
Phase Error Trace
comma-separated trace points in percent. The first value is the
symbol 0 decision point. The trace is interpolated for the currently
selected points/symbol displayed on the front panel. The number of
trace points depends on the current measurement interval setting.
Measured Polar Vector IQ trace
polar vector IQ complex data array, as comma-separated trace points
in dB. The first value is the symbol 0 (I component) decision point.
The second value is the symbol O (Q component) decision point, and
so on. The trace is interpolated for the currently selected
points/symbol displayed on the front panel. The number of trace
points depends on the current measurement interval setting.
