Hi,
I have been creating a Tool to download NVMEM data from the Agilent 34410A device, the original Driver for this was not good in terms of timing out as all the data was not retrieved in a timely manner, so I modified the driver to account for the delay by adding other reads at 200k bytes this gave 50,000 counts to cover all of the readings. I thought I would post the solution below if this is helpful for future.
