Acquisition
Probe Dialog
The Probe Dialog immediately to the right of the Cn dialog displays the probe attributes and (depending on
the probe type) allows you to AutoZero, DeGauss and make tip selection for probes from the touch screen.
Other settings may appear, as well, depending on the probe model.
Caution: Remove probes from the circuit under test before initializing AutoZero or DeGauss.
Auto Zero Probe
Auto Zero corrects for DC offset drifts that naturally occur from thermal effects in the amplifier of active
probes. Teledyne LeCroy probes incorporate Auto Zero capability to remove the DC offset from the
probe's amplifier output to improve the measurement accuracy.
DeGauss Probe
The Degauss control is activated for some types of probes (e.g., current probes). Degaussing eliminates
residual magnetization from the probe core caused by external magnetic fields or by excessive input. It is
recommended to always Degauss probes prior to taking a measurement.
