Overview
The CAEN Mod.A1427 is a fast and low noise current preamplifier with AC coupled input. It hosts two outputs: EOUT (unipolar) that can be integrated to calculate the energy associated to the input signal and FOUT (bipolar) that can be used to calculate the rate of the input signal, discriminating the negative pole using the A1428 discriminator that is specifically designed to fit with A1427. The discriminator thresholds is settable from -1 to -100 mV via a 10 turn rotary handle with lock.
A1427 Kit configuration is also available, it includes the A1427 and the A1428 assembled together, both for fission chambers and for proton recoil detectors.
