A couple of years ago, I did a review and teardown of a tinySA Ultra spectrum analyzer. That tinySA Ultra was a ZS-405. I recently got my hands on an upgraded version — the ZS-407, and in this blog post,…
tinySA Ultra is an affordable spectrum analyzer geared towards HAM radio operators, RF enthusiasts and electronic hobbyists. With the Ultra mode enabled, it boasts a calibrated frequency range up to 6 GHz and can observe signals up to 12 GHz.…
While I was making a video on how to use HP 8671A as the frequency reference for an improved version of my simple DIY tracking generator for my HP 8566B spectrum analyzer, my spectrum analyzer suddenly decided to call it…
I got a couple of Microsemi’s C900502 10.525 GHz X-band Doppler radar motion sensors a while ago. This batch was made in UK and had “UK patents 2243495 and/or 2253108 apply” printed on the case. I have seen a teardown…
In this blog post, I will show you how to build a 0 to 5.8 GHz tracking generator for the HP 8566B 100 Hz to 22 GHz spectrum analyzer using off-the-shelf components for under $100. Although this tracking generator is…
In this blog post, Let’s take a look at how to measure a filter’s frequency response using a spectrum analyzer and a signal generator. Typically, a tracking generator is preferred for this kind of scalar network analysis as its center…
The latest addition to my lab is an HP 8566B spectrum analyzer. This isn’t just any spectrum analyzer, it was perhaps the best spectrum analyzer money could buy back in the late 80’s. While it was discontinued in 1997 and…
