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.
