Hi Yves, here are my results. 1) HP 83522A set as yours, also about the same parameters on my SA. The trace is similar, but much noisier than yours. 2) Hp 86222B (same frequency range) plugged in

Hi folks, problem solved. Previously, I only checked the GPIB addresses of present instruments. I have now set the GPIB addresses of not-connected units (like the second source which I don't have) to

Yeah, I have heard of the battery issue, thats why I removed the battery altogether... :-) No problem from that side! cheers Martin

The 8350B sweeper has a nicad battery (BT1), ...borrowed from the HP35 calculator family... mounted on the inside panel of the sweeper plugin compartment. By design, it gets trickle charged to

It is Germany. Seller chatted with me on Ebay messaging and said he will provide instructions in English. I asked for the BOM to see if anything unusual for US sourcing, which he promptly

Hi Martin, You wrote "Only the 83522A is greeted by the frame with 8.4GHz instead of 2.4.". No doubt the dip switch near the left front of the 83522A is incorrectly positioned. If you have an

I do prefer the HP 11713A (I have 2 of them) and the 84XX attenuators (I have an 8494H and an 8495H). I've actually accidentally dropped one of the attenuators, and it's still working perfectly! Not
