5.7.3 Analysis of differential signals
Before analyzing the output waveforms of differential signals, make sure that the P and
N signals are correctly aligned. If necessary, use "Horizontal" > "Skew" to deskew the
input waveforms.
For all output waveforms of differential signals (differential, common mode, P, N), the
usual analysis methods are available:
●
Trigger on differential, common mode, P, and N waveforms.
If the differential signal is enabled ("Enable" = on), all possible output waveforms
are available as trigger source, even if they are not selected and not displayed.
●
Zoom
●
Cursor measurements
●
Automatic measurements
●
Histogram
●
Mathematics. In formulas, use DIFF1, DIFF2, COMMON1, COMMON2.
●
FFT, spectrogram
●
Mask test
●
Export of waveform data. You can export the differential and common waveforms if
they are selected as output and displayed. Raw data is not available.
P and N waveforms can be exported if they are selected as output and displayed
(source = input channel).
5.8 Digital filter setup
After processing by the A/D converter, the channel and trigger signals are digitized sig-
nals. These digitized signals can be filtered to reject high frequency - also known as
