Re: HP 8595E SYTF 5086-7803 PIN switch problem
I have a similar problem with a HP70908A RF section. The low band is 10 dB (from memory) down once it has warmed up. This is either a bad diode or bad bond in the YIG module... I came to the same

Re: Help figuring out my 8648C Signal Generator?....
Hmm, that front panel model is impressive! Perhaps I should revisit Rhino, I looked at it many years ago (>14) but just couldn't seem to get my head around using it as a 'parametric' 3D CAD, somehow I

Ha ha, I've been using Rhinoceros 3D for about 20 years now. I'd consider myself 'ok-ish' at it. Just hobby use but I can usually get done what I need with it. I might be open to helping design some

Re: HP 8116 doesnt reach 50MHz properly
I assume you mean 8116A (not 8116). The 8116A can make it to 50MHz.? But it has a specified rise/fall time of <7ns (I measure 5.6ns on my unit), so this will make square and triangle waves look like
