SIS8800 MTCA.4 histogramming scaler/multiscaler/counter

The SIS8800 is the MTCA.4 follow up unit to the SIS3820 VME scaler. The unit comes with a 20 pin header connector for the control section and a 34 pin header for the counters (ECL and flat cable TTL version) or via 8 LEMO connectors for the control section and 16 LEMOs for the counter section (NIM and LEMO TTL version). Additional single ended or differential inputs can be fed to the scaler via a rear transition module (RTM). The SIS8800 accepts frequencies of up to 200 MHz on the front panel inputs in ECL and NIM configuration.
