TDS-380 NVRAM Backup via GPIB?

[reject902]

I had posted this over in the Tek forums last week, but didn’t receive any replies so I thought I’d give it a try here.

I recently acquired a TDS-380 in working order, with the old Dallas DS1644-120 still ticking and clinging on to the calibration constants.

I was wondering if there’s a method for me to backup this NVRAM via GPIB before the battery in it finally gives up. I’ve been searching around the forms here, and can see people who have had success with other scopes in the 500 and 700 series, but didn’t see anything on the 300 series.

I do have access to both NI ISA and PCI GPIB cards, and also access to older pentium class machines to work with on this.

Thanks
