Probes
LeCroy provides a passive probe for each WaveAce oscilloscope channel.
Probe Compensation
Passive probes must be compensated to flatten overshoot. This is
accomplished by means of a trimmer on the probe body.
1. Attach the connector end of your probe to any channel.
2. Connect the probe end to the CAL output connector at the front of
the oscilloscope.
3. Adjust the trim pot on the probe body until the square wave is as
flat as possible.
4. Set the Probe option attenuation to 10X by pressing the Channel
button and then the Probe menu button.
5. Set the switch to 10X on the probe.
6. Attach the probe tip to the PROBE COMP～3V connector and the
reference lead to the PROBE COMP Ground connector. Press the
corresponding channel button, and then push the AUTO button.
7. Check the shape of the displayed waveform as follows:

Setting Probe Attenuation
Probes are available with various attenuation factors which affect the
vertical scale of the signal. Push the Channel button and then the Probe
menu option button.
