The program outputs a 2kB (or 2 x 32kB) binary ROM image files files along with a couple of ASCII format files of the data. 2kb for CAL ram and 32kb for DATA ram (probably not needed, but it can dump the data RAM chips). The binary files have the extension .hi and .lo (CAL ram data is only in the high byte of the memory space).

Hi Mark, I had success using your HP3458.exe on my HP3458A! I just backed up my CAL data a few minutes ago. I have been interested in doing a backup for several years but kept putting off buying the GPIB to USB adapter. I have been using a NI GPIB-ENET/100 for some years now and so your program was a way for me to backup CAL ram at no cost. The only preparatory steps I needed was to test my GPIB connectivity with NI Measurement & Automation Explorer's Communicate with Instrument function. Then I Reset the 34358A and set END to Always. I had NI's I/O Trace on the whole time just to keep track of everything. I think the NI 488 software is a free download. Thanks for all the work you did!
