12. Principal Features The Richter is a multi purpose multi channel 16 bit data acquisition and streaming system providing simultaneous and synchronous sampling of all inout channels with sampling rates of up to 10 MS s Model Richter16 10 The unit is primarily operated in a continuous streaming system with acquired data streamed directly to disk It may also be operated in triggered acquisition mode if used in conjunction with the Trigger Hit Count THC System with the acquired triggered events stored on the data acquisition system hard drive Multiple 4 channel Richter units can be synchronised master slave setup together to provide a full expandable system with up to 20 channels using a single master slave bridge card which provides the output clock and trigger signals for data synchronization between the Richter units using external cabling The Richter units can therefore be used in either a independent streaming b master slave streaming c independent triggering or d master slave triggering Integrated with ASC s data acquisition and hardware control eXstream16 software version v1 2 2 at the time of editing this manual for the PC based Richter unit provides a complete data acquisition solution The 3 dB bandwidth for the instrument is dependent on the input impedance i e 50 Q or 1E06 Q of the data acquisition card For the PCI 9816H DAQ card used in the Richter Model Richter16 10 the 3 dB bandwidth is 5 1 MHz
