Hello, there was an issue with NI-DAQ 6.9.2 that was not in previous versions of the NI-DAQ driver regarding the offset nulling routine for the SCXI-1520. This problem was fixed, and a patch to the NI-DAQ driver is available.
Please contact National Instruments
Technical Support for a copy of this patch file.
The NI-DAQ 6.9.2 driver with this patch file is the optimal version for use with the SCXI-1520. The offset nulling routine has been optimized to take less time, and to perform a hardware null to extremely low (if not zero) voltages.
