used to prevent any electrical shock. This also helps to avoid unwanted
interconnection between the two probes when both ground clips are
connected.

An example of how a fully isolated input channels handheld scope monitors the
output voltage of a PWM inverter drive and the gate control signals of an
Insulated Gate Bipolar Transistor (IGBT) is shown in
connected to the output voltage of the PWM AC drive and Channel 2 is connected
to the transistor input, where the signals come from the control board. For a
complete floating measurement, the probe reference lead for each channel is
connected to the circuitry.
