My aged, but otherwise working SG (100kHz to 1000 MHz) has a long-standing glitch in the RF output. settings? While not a deal-breaker in normal useage, I'd like to fix if possible. With 1dB steps

Hi John, I didn't see that it was a big error in the title of the topic. I was still continuing to speak about the 8670 family instead to remark that it was a mistake from the first post in the

John - re the Google workflow This is new to me, and interesting, but before I head down that rabbit hole do you know how it handles non-English language? My current problem is a trove of vintage

Many thanks for that suggestion, Peter; much appreciated. Clearly those keys are in need of cleaning in any event, so that needs doing anyway. It'd be a real bonus if it clears the issue as

Okay, "Response" and not "One path two-port" then. I'll give that a try tomorrow. One other point, though: you say to choose 'thru' and connect a 'thru' standard. Surely a 'thru' is a basically a

Thanks for sharing! If I may add: for anyone like me that had just the basic unit without the LAN option, it's a fairly simple

Yes, it can. I’ve had several similar type HP front panels do that. Disassembly, lots of q-tips with IPA cleaning panel holes and keys then putting everything back together solves it, if that’s

David, Just to be clear: This is really an 8760B, right?? (Not an 8670B) I think the photo you posted makes that clear. --John Gord

Excellent information! Thanks!

This post is in the category of ... I doubt anyone else will need this but if you do, here it is! The 1660/1670 series logic analyzers have the ability to do disassembly of captured microprocessor

First guesses a power supply out of spec or noisy or a stuck key. Peter

I'm at work so I don't have my VNA with me. The trick is to activate the S21 trace (press parameters, then S21, make sure it's showing the uncorrected S21 trace) then bring up the Cal Menu. Then

Hi guys, In the course of investigating some IFTs today, I fired up my 8596E, which started-up normally and displayed the usual min thru ~12Ghz spectrum. However, when I tried to enter the frequency

Yes Yves, I did Google before posting. The first link you gave is for the full 'Reference' Manual (not Quick Reference Guide). The second is for the one I described (poor quality scan). I'm looking

Okay, I've hit a bit of a brick wall with the calibration. It was suggested a through calibration for S21 would be sufficient for this test. However, the choices under the calibration menu are causing

Thanks Mike - the discussion on eevblog forum is very helpful and I appreciate you providing the link. I didn't realize (until reading that thread) that the switch uses GaAs switches, not PIN diodes,

I do the same. It also allows one to clean up the document, particularly to remove fold shadows, spots and other minor but annoying defects. DaveD -- This email has been checked for viruses by
