Counting Unit – STM4011

SIMTRUM offers the STM4011 counting unit includes counting control circuit and upper computer acquisition software. The counting unit can be used directly in combination with a photon counting detector or scintillation detector as a counter. The counting software has a simple and easy user interface.

Feature

Count the positive logic TTL level pulses and input them to the computer through RS-232 interface
Gating time is adjustable
Built-in linear correction program (for use with photon counting detectors)
Serial port baud rate: 19200 (1 bit start bit, 8 bit data bit,1 bit stop bit, no check bit)
