ni usb-6009 and ni usb 6210

[word505]

Recently I've used an Ni-USB-6009 to get voltage readings on a device Im using, Using a vi that I wrote. However My company wanted me to be able to get more data points in a specified time so I purchased a faster Usb- 6210 and hooked it up the same way. The Ni-Usb-6009 at a rate of 48000 reads 800 samples and the 6210 reads 250,000 with 2500 samples. I hooked up the 6210 and it would not allow me to read at that higher rate so I was like hmmmm. let me put the same info in for the 6210 as I would for the 6009. I should get the same readings for both but I did not. the 6009 ranned like sewing machine however the 6210 gave me all different types of readings and even flat line a coupleof times  Why would this happen if these are the same devices?????????

Can you attach your code?

Hello word 505,

According to the specifications of the USB-6210, you should be able to acquire at 250KS/s if you are using one channel. According to your description you are not getting any error code but an unexpected behavior. Try to use one of the LabVIEW examples for finite acquisition to check if it works fine to discard code errors.
