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 ...

An Atmel AT90S2313 is being used on this frequency counter project along with 3 HC TTL chips and 3-digit 7-segment displays. An Atmel AT90S2313 is being used on this frequency counter project along ...

The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 ...

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has developed a broadband and high-precision terahertz (THz) frequency counter based on a ...

The Model 1856C frequency counter is capable of measuring from 5 Hz to 2.4 GHz and features a special 50½-terminated input for use in with VHF, UHF, microwave, and cellular telephone systems. A ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...

The author is a broadcast contract engineer who has a unique way of measuring the carrier frequency of the AM stations in his care. Making off-air frequency measurements of AM broadcast stations can ...

Sometimes when you build something it is because you have set out with a clear idea or specification in mind, but it’s not always that way. Take [kodera2t]’s project, he set out to master the ATtiny ...

Compact and lightweight, the Model 1856D frequency counter covers a wide frequency measurement range of 0.1 Hz to 3.5 GHz to address a broad spectrum of laboratory and service applications. The unit ...
