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 ...
The project utilizes an AVR controller that can be used as a counter by being more involved with a PIC which has synchronous counter input. The PIC input can handle frequencies up to 40MHz.
Frequency! It’s an important thing to measure, which is why [Jacques Pelletier] built a frequency counter some time ago. The four-function unit is humble, capable, and also an entry into our 2025 One ...
