Re: Unknown component on HP1345A monitor
It might be Sprague 173D225X9020V Capacitor-Fxd 2.2uF 10% 20V TATBSA. That is what is shown in the display section parts list for my 3577B. They apparently did not see fit to include C49 on the three

Re: 6502 inverse assembler for 16700 series LA
A long time ago I wrote a disassembler for 6502, and I still have the source code. It's written in Basic so shouldn't be too hard to port to a modern platform if you want it. My use for it was to

6502 inverse assembler for 16700 series LA
I know there was some partial 6502 disassembler support for the 16500 series. ?Has anyone ported it or something else to the 16700? Thanks, Marc Howard

Re: Mating APC 3.5 with APC 2.92 connectors
Hi Dave Thank you for the Paper Regarding connecting SMA to APC 3.5 or 2.92 the problem is the SMA and who made it as a lot of inferior SMA when we are talking about working above 10 Ghz are only fit

Re: Unknown component on HP1345A monitor
Yes, it appears to be a 2.2uF 20V tantalum. According to the PCB silk screen it is identified as C49, which on the parts list identifies it as such (A1 C49). If this is a bypass on the -15V supply,

Alright, I can¡¯t resist: With China, you get what you pay for. Sometimes you pay (extra) for quality you don¡¯t get, but expected when you paid a premium. All that said, part of the problem is

Unknown component on HP1345A monitor
Hello :) I had a -15V supply short circuit on the XYZ board of an HP1345A monitor. I found this to be faulty but it is an unknown component and does not exist on the documentation. It is written on it

Re: Mating APC 3.5 with APC 2.92 connectors
Ah, that's why the HPAK 84904, 84905, and 84906 40 GHz attenuators come with 2.4 mm connectors instead of 2.92 mm K connectors.? And why we have 2.4 mm connectors on Keysight gear at work.? Thanks

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
