In this video, I take a look at the classic 5343A Microwave Frequency Counter. This unit can measure frequencies up to 26.5 GHz and uses a heterodyne harmonic architecture.
Thank you for another interesting video and glad to have you back! I agree with you about the manuals, lots of good information in those theory of operation sections. I recently finished repairing an HP 5350B that uses the same harmonic heterodyne technique - I was very lucky to find a working sampler for the front end which was damaged. I also added new and slightly brighter LEDs to the display.
Nice - Did you see Kerry Wong's video on adding a better backlight - ua-cam.com/video/i9UGBLvTsNs/v-deo.html -If yours came out that well I might try it for my 5351A
I replaced the broken gate control on a 5342A in a video some time ago, the actual pot value wasn’t that important if I remember rightly, looks like you just need a knob for it.
Welcome back! Great to see another video. I always enjoy your content. I hope you keep it up if you find the time.
Thanks - Appreciate it.

Good to have you back!
Thanks - Appreciate your comment.
Dishwasher part number 5343A
I had bad tantalum caps in both the 5342A I worked on, my guess would be that needed them replaced too
Probably - I'll have to go watch your video on the 5242A again.

Yep - Haven't looked for a replacement yet but I have the manual so I can look up the actual part number and see what comes up out there.
