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 ...

Get to really know the fundamentals behind your test equipment. Not only do you reap the most out of your scopes, etc. as well as avoid debugging traps—it can also facilitate a “spec hack.” Everyone ...

Oscilloscope bandwidth is a tricky thing. A 100 MHz scope will have a defined attenuation (70%) of a 100 MHz sine wave. That’s not really the whole picture, though, because we aren’t always measuring ...

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 ...

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 ...
