| counter/timer module CT2 data sheet 1 description The CT2 counter/timer module converts a PC into a high performance pulse counting instrument. The module has a 32 bit count capability and includes a microcontroller and RS232 interface to communicate with a host computer. Software supplied with the module makes the CT2 perform a sequence of count rate measurements as programmed by the user. The CT2 is supplied with software allowing measurements to be made immediately following switch-on. An ActiveX control driver is also provided to allow users to develop their own control software using LabView, Visual Basic, etc. A lead set including pc cable, powerand control connectors is included. | |||||||||||||||||||||||||||||||||
