Monitor Output
Characteristics
The monitor outputs are used for monitoring the high voltage signals
using low amplitude tools. In general, the gain, bandwidth, pulse
response and sinewave distortions should be very similar to those
characterized by the main outputs however, since the outputs are
used for monitoring purpose only, some of the characteristics are
relaxed. Each channel has its own monitor output and therefore, the
characteristics are tested on each channel separately.
