9301-P Fast Preamplifier

The Model 9301-P low-noise, fast-rise-time Preamplifier has been designed for use with photomultipliers, electron multipliers, and other detectors employed in photon counting, ion counting, or fast-timing applications. When connected to the detector, the 50-Ω input resistance of the Model 9301-P provides a load resistance for the detector output current pulse. 

In addition to its fast rise time of 1.5 ns, this preamplifier has a voltage gain of 10 and an output impedance of 50 Ω. Because of its compact size and light weight, the Model 9301-P is ideal for mounting directly or close to a detector. Consequently, low-level signals, which 
would otherwise be susceptible to pickup of noise or interference, are boosted to a suitable level for cable connection to the main amplifier. Connection to a power supply is through the 3-m (10-ft) long captive power cable furnished with the Model 9301-P.

Model 9301-P is fitted with a power cable connector (Amphenol 17-20090) that is compatible with other NIM standard modules.
