The Model VT120-P Fast-Timing Preamplifier is a high-performance, widebandwidth preamplifier designed for boosting very fast linear signals from microchannel plates, photomultipliers, electron multipliers, silicon detectors, and other detectors used in fast timing applications. The rise time on all versions is <1 ns with a 5-V output, enabling excellent timing resolution. The Model VT120-P is a single-channel unit in a small preamplifier package. It is available with a gain of 200, noninverting (A version); a gain of 200, inverting (B version); or a gain of 20, noninverting (C version). BNC connectors are used for signal connections on the Model VT120-P. A cable is available (Model C-VT120-P for connecting power between the Model VT120-P and conventional preamplifier power outputs using Amphenol-type 17-80090 connectors.
