Leo, Will be good when you have already open A24 module to write-down state of the pins 8, 9 and 10 of U313 in function of the frequency bands. Milan

I'd sign up for a replacement board or even just the gerbers so I could get my own made instead of using your time. In fact I'd probably just be happy with the schematic, parts list and instructions

Good job Leo! Milan

Hi Ed, I’ve done pretty much the same thing a few times with asst SA’s. ?You’ll find that the narrow bandwidth on the SA really isn’t that useful with an SA/TG combination as the DUT will

It's been chilly out again, and the 8568/85662 has been running stable since last night without any sweep-stopping, so I took the opportunity to work on the TG some more. I took some screen shots to

Thanks to everybody for great discussion.? Despite initial diversion I have found that U313 Agilent 1GC1-4210 has struck yet again.? It had weird failure mode where it would change its division

No way - I will lose them before I die. Or at least I hope that's the case, since otherwise I would have a pretty short lifetime! I had a feeling they might be 0.05", as they looked the same as the

Dave, Go for Wiha 353.92 (metric) and 353.93 (imperial) set. Its for the life investment. Milan

If anyone here wants to try, I have a few spare E5515Cs here. I bought them opportunistically; I have two in my lab which I use for actual cellular equipment development. (*gasp!*) I will not

Adapting a 8922 for amateur (analogue) use would be more about re-writing the software than changing the hardware. Another issue is that while the signal path is fairly wideband the calibration data

PM sent. Haven't figured out any way to confirm that in the groups.io interface; PEBKAC perhaps :-<.

Rather than easiest or hardest, how about luckiest? I was given a 50" plasma tv once where the top half of the display was dead and the bottom half worked fine. Once I got inside I could see that the

I have a number of tracking generator projects in the works, over years, for the 8566 SAs. When I acquired a couple almost-working 8568s a few years back, I figured I'd make one for them too, if I got

I think it would work more than fine as a little bit of JavaScript running in the browser on mostly anything. After all, the era of intelligent terminals is back with vengeance. You can program them

Great stuff. I have a copy of that book, and am looking for the actual software.

Hello, Tom-- I encountered ECAP via an university's IBM 1620, which offered 24- to 36-hour turnaround. That made for slow debugging. Maybe someone with time on their hands could recode ECAP for a

I've got the 8568 "working" now with a different IF/display unit, and it's pretty much the same behavior - OK when nice and cold, then the sweep stopping and other problems if it's warmer. I'm taking

From what I see the differences in models is mostly in the power handling of the front end. There are other cell phone features between model variants, but, those do not concern me too much. I am
