Now I am using PXI 6052 E Daq card with Real Time Controller ( P3 and 833 MHz Processor with 512 MB Ram runns LabVIEW RTOS). Controller runns one time critical loop at 1ms rate. I am setting Daq to acquire 20,000 Samples/sec. Every ms I am reading 20 samples using Read AI mx VI. It takes ~250 microseconds to complete the read operation.
We want to go for M series because of it's low cost. Preferably M Series PXI 6229. This card can offer same performnace and data rate? ( means AI Read completes within 250 microseconds?).
