USB DAQ devices feature highly advanced counter/timer
29 June 2014
Measurement Computing Corporation has introduced two high-speed USB counter/timer data acquisition devices available with four or eight counter I/Os.
The USB-CTR Series, which are now available in the UK from Adept Scientific, feature high-speed pulse counting with a 48MHz maximum input frequency. Resolution is programmable up to 64 bits per counter, with an aggregate scan rate of 8Mb/s.
These affordable new devices offer some of the most advanced counter/timer functionality available in USB DAQ today. Supported high-level input modes include totalise, period measurement, pulse-width measurement and timing measurement. Four independent PWM timer outputs and eight digital I/O are also provided.
Timer output channels can operate continuously or for a specified pulse count, with duty cycle and period changeable on-the-fly. Counter and digital channels can also be scanned synchronously. Flexible edge, level, direction, and de-bounce filter settings allow the counters to better adapt to user signals.
Software options for the USB-CTR Series include comprehensive support for Visual Studio and Visual Studio.NET, DASYLab and NI LabVIEW.
