The PAS is an expandable multi-channel (up to 36 channels) system that consists of the Pulser Amplifier Desktop units (PADs) and Pulser Interface Unit (PIU).
The PAS provides pre-amplification and switching between pulsing and receiving mode for all transducers in a multi-sensor array during an ultrasonic survey.
Each PAD has selectable gains between 30 and 70 dB, and a broad frequency response with a plug-in filter circuit to tailor the unit to the desired frequency range. The unit is software controlled over the PC USB interface.
