Product Description

Current Mode Preamplifiers convert the current output of a photovoltaic Ge, InAs, or InSb detector into a voltage output. They amplify the signal for subsequent use with oscilloscopes, lock-in amplifiers, or A-to-D converters.  Three different preamp models each offer specific advantages, depending on detector type and bandwidth requirements. All units (except multi-channel models) have switch-selectable gain.

The PA-6 is a general purpose preamplifier recommended for intermediate shunt resistance (400ohm<RD<50Kohm) detectors, including large area J16 Series room temperature Ge. The PA-6 has very low voltage noise and offset voltage, which significantly reduces low-frequency noise and DC drift. Standard gain settings are listed in the specification table below; custom gain settings are available.
