In my previous design idea, a design for a simple GPS disciplined oscillator (GPSDO) 10 MHz reference was presented. A note at the end of that article describes the realization that a frequency ...

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 ...

We think of digital displays as something you see on relatively modern gear. But some old gear had things like nixies or numitrons to get cool-looking retro digital displays. The HP 521A frequency ...

With regard to retro test gear, one’s thoughts tend to those Nixie-adorned instruments of yore, or the boat-anchor oscilloscopes that came with their own carts simply because there was no other way to ...

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 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 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 ...

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 ...
