Tranfer Rate of MXI 4

[Venkat Narsimha]

The Sustained Transfer Rate of MXI 4 is 78Mb/s, I need to check if Iam able to Transfer the Data really at that rate, is there any program or Utility to prove the Same.

Hey Venkat,

A few things I wanted to mention:

1) These specs were verified by R&D, and usually, we're conservative with our specs. You can see from the specs listed below that at a fast rate, it can sometimes achieve a speed of 132 MBytes/sec (not sustained, but conservative on that aspect as-well)

2) The transfer rate would be 78MBytes/s so 8 times faster.

3) If you were to perform a simple data aquisition at those speeds, you should be able to test it. I would recommend opening labVIEW, put down a Daq Assistant, and try to transfer at those speeds. If you had a 16 bit card, remember that that is 2 bytes. So it would be 78,000 / 2 Hz for a 16 bit card, and I would keep the sample size as-well so that labVIEW isn't a limiting factor. I would go ahead and keep the sample size at 78.000/2 as-well, so 1 sample is sent per second.

Regards,

Nick D.
