Mathematics
A parallel bus that is displayed as quasi-analog waveform can be analyzed with FFT. To
configure the FFT, use the "Advanced" mode and the formula editor.
Data export
The data of digital channels and parallel buses can be saved in the same way as analog
waveform data. One source waveform per file can be saved.

11.2.1 Using Digital Probes
Consider the following guidelines for good probing practices:
●
The ground lead from each digital channel group (D15–D8 and D7–D0) should be
attached to the ground of the device under test if any channel within the group is being
used for data capture. The ground lead improves signal fidelity to the oscilloscope,
ensuring accurate measurements.
●
For high-speed timing measurements (rise time < 3 ns), each digital channel probe
should use its own ground.
1. Connect the digital probe cable to any of the MSO connectors on the rear panel of
the instrument as shown on the Documentation Card delivered with the digital probe.
2. Connect the ground lead on each set of channels (each pod) with a probe grabber.
3. Connect a grabber to one of the probe leads.
