Is that the resistance of the bad connections?

Nothing fancy or real significant. You guys are reading WAY more into this than necessary. Oh, and mostly this occurred due to a HUGE government conspiracy to cover up the existence of an alien species that was sent to Earth to assimilate our independent fixed wireless networks. Resistance is futile.

Given the wording “increased the incidence of”, one could speculate that this issue has always occurred, either on some units or under some conditions, but with a low probability. I know I recently RMA’d a unit that intermittently showed this issue, and it was not on the serial number list. “Factory process issue” could be like that Proton rocket where they put the part in backwards and hammered it to fit. It could just mean someone loaded the pick&place machine with a reel of the wrong parts. What I can’t figure out is the significance of the term “Catalina”. I can find an old DSP company called Catalina Research, but no indications it was absorbed into Analog Devices or sold technology to them. Maybe it’s a cat name, like Sierra or Harley.

OK, crystal ball in lap.... “factory process issue”... Soldering most likely. Short, ground, bridge, open..... Could be a mis-aligned or misplaced chip too. Same difference. “that resulted in an electrical problem” Yeah, most physical soldering issues are truly an electrical (as opposed to software, firmware etc. problem) “which increased the incidence rate of voltage issue” OK, increased failure rate due to voltage issues. Solder opens normally do cause voltage (or lack thereof) issues. I still don’t understand what the meaning of “is” is... From: Matt Mangriotis Sent: Monday, August 24, 2015 8:17 AM To: af@afmug.com Subject: Re: [AFMUG] Field Service Bulletin - PMP 450 SM There was a factory process issue that resulted in an electrical problem which increased the incidence rate of voltage issues with the Analog Devices RF chip (the “ADI” chip). It won’t affect ALL the units listed, but we don’t want to take any chances. The issue has been root caused and corrected.
