Re: Mating APC 3.5 with APC 2.92 connectors
China is easy to misunderstand. Sadly, I am not allowed by NDA with a client to go into detail. Let me ONLY say that - while bashing the Chinese gets you brownie points with the good looking

Dave - absolutely agree! IMO we (US) seem to have a bit of a learning problem and have not demonstrated the capability of LONG TERM LEARNING. Cheers! Bruce Quoting Dave McGuire

Re: Mating APC 3.5 with APC 2.92 connectors
There certainly isn't. And I'm sure that wasn't appreciated by any of the respected, educated engineers here who happen to be Asian. We are unified here by the purity of engineering, and common

Re: Mating APC 3.5 with APC 2.92 connectors
The Chinese make lots of truly excellent stuff. I've had occasion to work with Chinese engineers a few times over the last decade or so, and I've been very impressed. However, us stupid Americans

Re: Mating APC 3.5 with APC 2.92 connectors
Calma chicos :) there's no need for inappropriate language here. Jeff, it has not much to do with the origin it of the parts. There are certain precision SMAs, yes. But they have a similar price tag

Re: Mating APC 3.5 with APC 2.92 connectors
Dave - THANKS - It is simply uncalled for. And YES some of the Chinese connectors are of poor quality - but part of the reason is that people insist on low prices. The Chinese do make some excellent

Re: Mating APC 3.5 with APC 2.92 connectors
REALLY Jeff - I DO NOT SEE THE NEED FOR THE USE OF DIVISIVE NAME CALLING. It s OK (IMO) to call out CHINESE connectors of poor quality, it is ABSOLUTELY UNACCEPTABLE IN THIS FORUM TO USE THAT TERM.

Re: Mating APC 3.5 with APC 2.92 connectors
Way back when in 1986,when I first purchased 2.92 Connectors from Wiltron ( the inventor, which was why HP did the 2.4, cause they couldnt stand buying connector from their competitor, Wiltron),

Re: Mating APC 3.5 with APC 2.92 connectors
Hi, unless you do some very critical work and need to see 50dB of matching... :) I'd say it will not matter in practical terms. I have never "seen" the transition in normal work And never directly

Re: LODA and TG 85644A
One thing I should also mention is the IF out connection on the rear of your 8593 should be terminated to 50 ohms when not being used. I noted on mine I would get level errors if it was left floating.

Re: LODA and TG 85644A
For adjusting the LODA in you 8593, refer to the service guide for 8590 series analyzers, assembly level repair manual. Pages 139-141 for options 09/10.

Mating APC 3.5 with APC 2.92 connectors
Hi, I know that APC 3.5mm and APC 2.92mm connectors mechanically mate. What I would like to know: What is the electrical impact of doing so? Background: I had the chance to measure some 3,5mm DUTs on
