This frequency counter is [Miguel Pedroso’s] entry in the 7400 Logic contest. After looking at the design we think this is a perfect project for those who have not worked with logic ICs before. The ...
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 ...
Image Credit: Allied Electronics, Inc. Frequency counters are digital devices for accurate measurement and display of square wave and pulse input signal frequencies. A frequency counter is an ...
Everyone loves a bargain. Who doesn’t love a hacked oscilloscope? Well, it would be unusual for an oscilloscope company to teach you how to hack your own hardware. Besides, that’s already been done ...
Description: Measurement range: DC to 3 GHz Input A/B (BNC): DC to 200 MHz Input C (SMA): 100 MHz to 3 GHz Input impedance A/B: 50 Ω or 1 MΩ (switchable), sensitivity 25 mV Input impedance C: 50 Ω, ...
The project aims to build a simple and easily-reproducible RF/Microwave frequency counter that is based around a PIC16F876A microcontroller. This particular frequency counter has three inputs ...
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 ...
B&K Precision has introduced a pair of 10 digit frequency counters reaching 3 or 6GHz, with ±1ppm stability across their +5 to +40°C operating range. “This series utilizes a reciprocal counting ...
