HP Series Submersible Preamplifier - Order Code HP1
Description
The Submersible Preamplifier is an essential part of the hydrophone signal as it buffers the signal and provides a 50 Ohm source. It connects either directly to an Interchangeable Probe ('HP' series), or, if required, via a 20dB In-Line Attenuator (A20/1). Power is provided by a DC Coupler (DC1) so that the dc power and the acoustic signal share the same conductors in the interconnecting coaxial cable between the preamplifier and the coupler.
