You are correct. Good that you have most of the pieces. Tom Holmes, N8ZM Sent: Tuesday, April 29, 2025 4:45 PM To: [email protected] Subject: Re: [HP-Agilent-Keysight-equipment]

I have been talking to people today about the Tegam 1830 A and as yet I cannot find anyone in the UK that has actually sold one or used one I assume those that are using the Tegam 1830 A are talking

I have found the installation image for HP Basic for Windows 6.33 on the internet archive From the images in the archive it looks as though there were a number of printed manuals that were supplied

Oh, I got it :) Sorry for my confusion! Thanks Tom, I think what you are talking about is converting 85102b (IF detector as part of 8510) to 85102R (microwave receiver called 8530A). I already have an

IIRC is “If I Recall Correctly”. Sorry for the shorthand. I’m going from memory from when I did a conversion from an 8510C to an 8530 around 1999, and I recall replacing three IF boards and the

Hi Tom, I already had 8530A microwave receiver and 8511A frequency converter. But I don't know what is it "IIRC"?. And what sweep trigger board is also required? Thanks, Wojciech

Thank you Razvan for that information. I didn't know that. You are right, it would be too easy to be feasible. When the security fuse is programmed, the array will read as if every fuse is

Are you aware that the 8530A also uses different IF and, IIRC, also the sweep trigger board? From Tom Holmes, N8ZM

The contents of the PAL chip cannot be "downloaded". You will need to find a chip on eBay or from another 8510C that has the 8530A option. Regards, Razvan

Dear Colleagues, Does anyone of you own an 85101C display unit with *option 011* and would be able to download the contents of the PAL security key *08530-80004* (option for the 8530A microwave

For a fairly advanced reference, I think it would be possible to replicate the 50 MHz oscillator in a typical HP power meter from the 1970s or 1980s. This would be a weekend project rather than someth

Another missvalued instrument is HP434A… I connected it to an external voltmeter and workd very good as direct transfer to DC to RF … Ing. Patricio A. Greco Taller Aeronáutico de Reparación

I think many people effectively do just that by being able to check and adjust the 1mW reference on a modern power meter using the 432A and the DC substitution method. However, my setup has that

Hi, I have a issue with keysight MSOS254A Oscilloscope and it's FPGA version mismatch. As the error clearly shows the required version is 49172001, so can any one help me to find this firmware and

Hi, Guys, I need help to recover correct FPGA version. Can any one help me to find the required FPGA version(49172001), and guide me how to install this version. Thank you for your time and support,

Absolutely. I suffered the 432A through my PhD days and the repeated zeroing was a complete pain- but fine training in persistence for a “gradual” student. Regards, Alwyn

I have a couple of HP8478 sensors, no 478A. Is there any reason why the HP478A is advised/preferred and not the HP8478? 73 de Harke
