The great thing about building with gates is the crazy speeds you can achieve by using hardware directly (as opposed to working with simple microcontrollers). This 100 MHz frequency counter is a great ...
Here's news of a neat high-res frequency counter that's operable in either an IEEE-488/GPIB instrumentation environment, or across a Universal Serial Bus (USB) connection. Pendulum Instruments AB 's ...
The single-width 3U-sized P635 PXI frequency counter offers eight channels to monitor 0.06-Hz to 100-kHz pulse sources. The board provides TTL as well as differential inputs ranging from ±20 mV to ±20 ...
