I have several old 8340A’s, 8340B’s, 8341A’s, and 8341B’s that I'm interested in upgrading the firmware to use with some 8510C Network Analyzers that are coming-out of long-term storage. According to the 8510C service manual, these Generators need to be firmware revision 1992 or greater. So far, most of our assets appear to fall within the 1985 – 1988 vintage.
Does anyone still have documentation available about these firmware updates, and/or upgrade instructions?
I tried contacting the support e-mail for Keysight, and got this really confusing reply that didn't answer any of my questions. I'm hoping that the humans here, might give me better results?
