[volt-nuts] Firmware on HP 3457A - can it be upgraded?

[Dr. David Kirkby]

I've got a 3457A, but I have no idea of the firmware version, as it does
not report it when it powers on. I guess there must be some way to find
out, but it was not obvious from a few minutes playing with the buttons.

Does anyone know how to find out, or if it can be upgraded? I've just paid
for calibration on another instrument, and Keysight will update the
firmware for no extra charge.
