Hi,
I am using a USB SCXI-1600 with a 1102B, 1104C and 1581.
The SCXI chassis is a SCXI 1000.
I am using DAQMX 8.0 and LabView 7.1.
I have create 2 DAQMX tasks with MAX, one is reading all the channels of the 1102B and the other one is reading the channels of the 1104C (64 channels in total).
To read this 64 channels takes around 1s! Each task takes around 500ms!
The labview program is really simple, each DAQMx task goes into the DAQMx read VI set to "Analog 1D DBL NChan 1Samp" Mode.
At first, I thought I was not using a USB2 port on my PC but it was not the case.
I would be very greatful if someone knows how to make this 64 channels scan faster.
Many Thanks,
Chris
