Re: 8350B w/83590A repair advice

Re: 8350B w/83590A repair advice
No other plug-in right now. Not afraid of diving in. Work on HP stuff all the time. These plug-ins look like a challenge in the way they are packed full. Just noticed that the frequency is moving

Hi Terry - Yes, I believe that we did get the 'twin' 3460Bs that were listed a few years ago. I guess whichever of us gets the time to do the boards will then have to share with the other. I'll be
