HP8970 Controller/ROM

Julian All Messages By This Member #140225 I have a faulty 8970, and I am told the ROMs on the controller board may be faulty. Does anyone have a spare board, or the ROM chips with programme in? Regards, Julian, UK
John Miles All Messages By This Member #140261 A or B? The B EPROMs are on ko4bb.com, at least for "Option H18," whatever that is. I don't think I've seen the A firmware floating around. I just uploaded the standard 8970B firmware. Thought it was already there but didn't see it just now... -- john, KE5FX toggle quoted message Show quoted text -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Julian Sent: Monday, November 13, 2023 4:20 PM To: [email protected] Subject: [HP-Agilent-Keysight-equipment] HP8970 Controller/ROM I have a faulty 8970, and I am told the ROMs on the controller board may be faulty.

J. L. Trantham All Messages By This Member #140278 Just checked my 'files' and I found U1 - U13 files, both .BIN and .MOT, for the 8970A. Not sure where I got them as they date to 2007. Not my 'usual' label as I save from a unit I have. If they don’t come through on this email, I can post them somewhere or send them directly. Just let me know. If they are not correct, let me know and I can open a unit I have and 'harvest' them. Headed OOT early in AM and will be back after Thanksgiving. Hope this helps.

Ulf Kylenfall Member Profile All Messages By This Member #140296 Before replacing anything - Check all operating voltages on the digital board. Do NOT trust the test points on the PSU. I have encountered erratic behavior caused by to high internal resistance of some inductors that were parts of the supply voltage filtering, Ulf SM6GXV
Julian All Messages By This Member #140306 开云体育 Ok, thanks. I'll bear that in mind... Do you know if the ROMs are interchangeable between the A and the B? Mine's an 8970B. If you swap a board from a working one for my board, the working one still works in mine. So I think it's something somewhere on my board...

Julian All Messages By This Member #140307 Ok, they came through ok... It's an 8970B. Do you know if the ROMs for the A and B are interchangeable? The 8970 isn't here at the moment - Do you now what type the ROM ICs are? Julian toggle quoted message Show quoted text On 15/11/2023 01:01, J. L.

Julian All Messages By This Member #140308 It's a B. Are the ROMs interchangeable? The 8970 isn't here at the moment - do you know what type the ROM ICs are?

J. L. Trantham All Messages By This Member #140311 Julian, Just looked on KO4BB and there are several 'files' of 8970A ROM's. One of them states they are '2716'. I have not personally read and archived the 8970A ROM chips but I can do that if needed. Good luck.
