Measuring time-related data and counting events are basic to countless data acquisition applications, and they often fulfil critical timing functions as components of complex measurement systems. They’re simple in concept and specific in function, but essential in so many products and systems today.
Our friends at Measurement Computing, those developers of DAQ devices that match the best in industry in everything except price, have just come up with a couple of USB counter/timers with just about the most advanced functionality we’ve ever seen in such devices, yet they’re surprisingly inexpensive. High-level input modes include totalise, period measurement, pulse-width measurement, and timing measurement. 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 debounce settings allow the counters to adapt optimally to user signals.
You can choose between models with 4 or 8 counter I/Os. They offer high-speed pulse counting up to 48 MHz input frequency. Resolution is programmable up to 64 bits per counter, with an aggregate scan rate of 8 MB/sec. Four independent PWM timer outputs and 8 digital I/O are also provided.
