maximum number of bits transfered by GPIB-write command

[Donkey Rubarb]

I am writing a program witch transfers all data from the hp16500b, I get data but not all data.
The number of datalines to transfer (1 dataline is 64 bits long)
is above 500000 and it seems that I get an error if i want to use the
GPIB write vi for more than a million bytes?

The NI-488.2 driver is capable of transferring a very large amount of data. The driver should allow you to easily transfer over 1MByte of data. Typically the maximum transfer amount is limited by the amount of physical memory in your system.

What GPIB error are you getting? Could you attach an NI-Spy log of the problem?
