WARNING. To avoid electric shock or fire, keep the probe body and output cable away
from the circuits being measured, as they cannot provide adequate protection if they
come in contact with electrical sources.

Operating with an Oscilloscope

When the probe is connected to a Teledyne LeCroy oscilloscope, the displayed scale factor and
measurement values will be adjusted to account for the effective gain of the probe. The
probe's internal attenuation is shown on the Probe dialog, which is added to the oscilloscope's
input channel dialogs when a probe is detected.
Probe Volts/Div and Attenuation
The front panel Volts/Div knob controls the oscilloscope's scale factor and the probe's internal
attenuation to give full available dynamic range. Some transition of the scale factor will result in
a change of attenuation.
Offset
Offset allows you to remove a DC bias voltage from the differential input signal while
maintaining DC coupling. This ensures that the probe will never be overdriven while a signal is
displayed on screen and prevents inaccurate measurements.
The total usable offset of the oscilloscope and probe system is a function of the oscilloscope
V/div setting, oscilloscope offset at that V/div setting, probe attenuation, and probe offset at
that attenuation setting, and this total maximum offset may be calculated.
First, it is necessary to know the oscilloscope front end V/div setting with the probe
