we have problem using two Agilent 34405A via USB on the same computer. We have the same behaviour as stated here : ... -p/1037020

The serial number seem to be corrupted randmonly, and I event get a BSOD (blue screen of death) when starting one 34405A...

I've try to update the firmware to the latest one available (1.40-3.11) but without luck. Every time I get the error :

"Firmware checking condition set in engineer program is invalid (eg. wrong amout of firmware revision)."

The current firmware in the instrument is : 1.19-3.05

Is there something I can do ?

The serial number are : TW46250080 and TW46250022

Thanks you for a fast answer.
