3.1 Digital Demod Measurement
This trace is the frequency spectrum of the FSK Vector Time trace data. The
demodulator produces the spectrum by windowing and FFT the FSK Error Time
data. On this trace, the individual error vectors are plotted vs frequency.
Example
:DISP:DDEM:WIND2:DATA EVSP
Sets the second window data to FSK Error Spectrum
Mag Error (Carrier)
Available only when the demodulation format is any FSK type.
This trace shows the carrier magnitude error trace in time domain. This trace is
computed by comparing the magnitude, point by points, of the FSK measured signal
with the averaged magnitude.
Example
:DISP:DDEM:WIND:DATA MERR
Sets the first window data to Carrier Mag Error
ASK Error Time
Available only when the demodulation format is any ASK type.
This trace shows the time domain error vector trace data results. The trace contains
the computed error vectors between ASK Meas Time and ASK Ref Time at each
point in time. The values of the error vectors are usually plotted as a magnitude.
Example
:DISP:DDEM:WIND2:DATA EVT
Sets the second window data to ASK Error Time
ASK Error Spectrum
Available only when the demodulation format is any ASK type.
This trace is the frequency spectrum of the ASK Vector Time trace data. The
demodulator produces the spectrum by windowing and FFT the ASK Error Time
data. On this trace, the individual error vectors are plotted vs frequency.
Example
:DISP:DDEM:WIND2:DATA EVSP
Sets the second window data to ASK Error Spectrum
Response
Displays the trace data choices that show equalizer response results.
