In the quest for an accurate frequency standard there are many options depending on your budget, but one of the most affordable is an oven controlled crystal oscillator (OCXO). [RF Burns] has a video ...

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 ...

Do you remember your first instrument, the first device you used to measure something? Perhaps it was a ruler at primary school, and you were taught to see distance in terms of centimetres or inches.

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 ...

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 ...

In frequency counters, the gating time allotted for counting is often too short to resolve low frequencies. A phase-locked loop could be used to multiply the input frequency. But in some cases, the ...
