Our incredibly fast dual input ADC’s and TDC’s are now an industry standard enabling conversions of up-to 1.000.000 events/s.
The 8k resolution and two independent 500 ns SAR-ADC’s are suited for a wide range of applications. In the SVA mode they can even be used to sample slowly varying DC signals or levels.
The “dual channel” TDC’ - Model 7072T - converts time directly to a digital output. They offer improved performance and linearity specifications compared to separate TAC and ADC modules.
There is also the Wilkinson-type ADC, Model 7070 which is suitable for high resolution HPGe detectors. The four-channel version of the 7070 is the Model 7074 which offers four independent ADC’s in a single width NIM module.
Our Constant-Fraction discriminators are still state-of-the-art even after a more than 20 Year history.

The Differential CFD - Model 7029A - still offers the highest counting rate (>50 MHz) of any such devices.
Our Pulse-Shape Discriminator - Model 2160A - can be used to separate neutron and gamma particles, alphas and protons, electrons and alphas etc depending on the detector used.
FAST ComTec is also offering a line of HV-supplies. There are NIM versions as well as benchtop models. All have in common an exceptionally high power output and very low ripple and noise values making them ideally suited for high-resolution spectroscopy applications.
Take for example a HPGe detector which collected some condensation on the feedthrough to the preamplifier which causes some arcing. With a HV delivering just 50 µA a very distorted spectrum will be the result. Our HV supplies have the power to burn out the condensation and the effects on the spectrum are negligible.
