voltage exceeds this limit, the coupling mode automatically switches
from DC 50 Ω to GROUND. You then have to manually reset the
coupling to DC 50 Ω.
CAUTION While the unit does provide this protection, damage
can still occur if extreme voltages are applied

Bandwidth - Bandwidth filters are available at a variety of fixed
bandwidth settings. The exact settings vary by model.

Probe - Teledyne LeCroy's 1.85 mm and 2.92 mm probe inputs
automatically senses probes and sets their attenuation for you. For
each channel, the probe attenuation can also be set manually.
Pre-Processing Controls
Pre-Processing means "before Math processing." Pre-Processing controls
provide the following functions for your respective channel:

Averaging - Specifically performs continuous averaging or the
repeated addition, with unequal weight, of successive source
waveforms. It is particularly useful for reducing noise on signals
drifting very slowly in time or amplitude. The most recently acquired
waveform has more weight than all the previously acquired ones: the
continuous average is dominated by the statistical fluctuations of the
most recently acquired waveform. The weight of old waveforms in
