Demod Error
Displays the general demodulation error results.
Error Vector Time
Shows the time domain error vector trace data results. The trace contains the
computed error vectors between IQ Meas Time and IQ Ref Time at each point in
time. The values of the error vectors are usually plotted as a magnitude.
Example
:DISP:OFDM:WIND2:DATA EVT
Sets the second window data to Error Vector Time
Error Vector Spectrum
The frequency spectrum of the Error Vector Time trace data. The demodulator
produces the spectrum by windowing and FFT of the Error Vector Time data. On this
trace, the individual error vectors are plotted vs frequency.
Example
:DISP:OFDM:WIND2:DATA EVSP
Sets the second window data to Error Vector Spectrum
RMS Error Vector Time
Shows the time domain error vector trace data results. The trace contains the
computed error vectors between IQ Meas Time and IQ Ref Time at each point in
time. The values of the error vectors are usually plotted as a magnitude.
Example
:DISP:OFDM:WIND2:DATA REVT
Sets the second window data to RMS Error Vector Time
