Data
Sets the data source of the selected trace.
1.
Capture Data
Sets the displayed pre-demodulation data of the selected trace to time domain
or frequency domain.
When this data source is selected, I-Q, Q-Eye, I-Eye, and Constellation under
the trace format are grayed out.
2.
Meas Signal
Sets the displayed demodulation data of the selected trace to time domain or
frequency domain.
When frequency-domain data are selected, I-Q, Q-Eye, I-Eye, and Constellation
under the trace format are grayed out.
3.
Ref Signal
Sets the displayed reference signal data of the selected trace to time domain or
frequency domain.
When frequency-domain data are selected, I-Q, Q-Eye, I-Eye, and Constellation
under the trace format are grayed out.
4.
Demod Error
Sets the demodulation error measurement results of the selected trace.
1)
Error Vector Time
Displays the vector difference between the IQ measurement time and IQ
reference time at each time point.
When this data source is selected, I-Q, Q-Eye, I-Eye, and Constellation
under the trace format are grayed out.
2)
Error Vector Spectrum
Displays the FFT operation results of the vector difference between the IQ
measurement time and IQ reference time at each time point.
When this data source is selected, I-Q, Q-Eye, I-Eye, and Constellation
under the trace format are grayed out.
3)
IQ Mag Error
Displays the amplitude difference between the IQ measurement signal and
the reference signal at each time point.
When this data source is selected, only Log Mag(dB) can be displayed.
4)
IQ Phase Error
Displays the phase difference between the IQ measurement signal and the
reference signal at each time point.
When this data source is selected, only Linear Mag can be displayed.
