Electronics readout packages on a TDC basis: compact - fast - USB 2.0

NEW: Multichannel FLEXI-TDC optimized for multihit-measurements

A 48-fold multichannel Flexi-TDC optimized for multihit-measurements has been developed on basis of our fast Flexi-TDC-System. 6 GPX TDCs with 8 input channels each and with one of them per TDC useable as a free programmable time reference input channel offer a multihit aquisition of e.g. up to 84 pulses/12.5ns. Data transfer with a transfer rate of up to 3Mcounts/s in the raw data mode is done via USB2.0. The measuring rate can be increased by a flexible programmable data pre-processing within the FPGA (e.g. histogram memory). Beside the standard input level NIM also customer specific adaptions are possible (e.g. LVTTL, PECL, ECL). 

Also available now: 4-fold to 6-fold multichannel Flexi-TDCs with an increased histogram resolution of up to 30ps. These devices contain 1 - 3 GPX chips with an internal readout frequency of up to 20 MHz each and 2 input channels per TDC.

Beside the sophisticated developments for the ultrafast particle and x-ray detectors, Surface Concept extends its product spectrum by some useful electronics devices which may find interesting applications in labs dealing with measurement tasks in the range of some ten picoseconds.
