 If yes, you can dump  old firmware and give me. I check it on my  TDS540 (2.16e) if  it runs fine with  old firmware,  you can upgrade it to newest firmware.

It is possible, it works with Agilent, probably: You must enabled NI VISA in your agilent GPIB software. But, i didn't know about it, because i have only NI-GPIB stuff.
One member has checking my unified tektool with agilent  USB.-GPIB adapter and it runs good (and slow, normal by USB-GPIB)

The error was there from the start together with a few more that went away after recapping and cleaning.

between the front panel board and the processor board.

Maybe some of you could explain where the eeprom can be found because I've created lately a thread on the same topic https://www.eevblog.com/forum/repair/tds510a-backup-eeprom-nvram-firmware/ about the TDS510A.

Could it be that only from C serie or D serie, the eeprom were physically installed on the acquisition board then I2C read from the CPU board ?

Where are stored the acquisition board calibration on no suffix, A serie and B serie ?

Thank you in advance, Albert
