Delay in analog voltage using DAQmx

[kannan.blitz@gmail.com]

We understand there is a delay in data acquisition. I am using a PXIe-1084 chassis with a PXIe-8861 controller and PXIe-4302 for AI acquisition. There is a constant 69 ms delay in the data compared to the PXI chassis time. What could be causing this delay, and how can we resolve it?

Delta Sigma Data Converters have inherent data delay due to the filtering and this is documented in the specifications,

Check if the 69ms correspond to your sample rate in the above table.
