The Impulse Generator IPG800 is the high voltage supply to the seismic borehole source BIS-SH-DS. The energy is stored in capacitors which discharge through a mechanical switch. The lightweight IPG800 is incorporated in a robust PeliTM case.

The IPG800 is operated by a Remote Control Unit (RCU) which is used to start a pre-defined sequence of shots or to stop the operation. The RCU is connected to the seismograph to send an accurate trigger signal.
