An accurate way to calibrate a frequency source is to use a high-resolution counter/timer to measure the beat frequency, or phase difference, between the source to be calibrated and a reference such ...

Counter/timer hardware is a crucial component of most embedded systems. In some cases a timer is needed to measure elapsed time; in others we want to count or time some external events. Here's a ...

The project employs a sliding window for calculation of multiple frequency updates per second on this frequency counter and timer. The project employs a sliding window for calculation of multiple ...

Two multifunction I/O modules feature both digital I/O and counter/timer functions on a single PMC module. The PMC424 provides 40 digital I/O channels for transistor-transistor logic (TTL) and ...

The Model 2201, 255 MHz GPIB universal counter/timer incorporates a temperature controlled crystal oscillator that provides an internal oscillator stability of 1 ppm. Suited for laboratory and test ...

With a 555 on the BOM, you never know what you’re going to get. With 40 of the versatile timer chips in a build, you might just get something completely unexpected, like this 555-based eight-bit ...

The BusWorks line of high-density Ethernet I/O modules for distributed I/O and SCADA feature new isolated discrete I/O that also perform counter/timer functions. These inch-wide modules provide an ...
