Preparing the Oscilloscope for Use
To use the digital probes (mixed-signal oscilloscope only)
5 For high-speed signals, connect a ground lead to the probe lead, connect
a grabber to the ground lead, and attach the grabber to ground in the
circuit under test.
6 Connect the ground lead on each set of channels, using a probe grabber.
The ground lead improves signal fidelity to the instrument, ensuring
accurate measurements.
