Is nobody use a PXI-6052E to acquire scan at low frequency ?? When I try to create a scan of two samples per scan (sample scan at 100hz) the ScanStart function return -10697 (rateNotSupportedError)!

The frequency parameter given to the ScanStart function are the followings:
- sample base = -1 (200ns)
- sample interval = 22 727
- scan base = 1 (1?s)
- scan interval = 10 000
This parameters should work but there is a problem.
If you had an explanation...
Thank you

You are getting that error because the E-series boards only support either 100KHz or 2MHz Timebases.

Double check the NI-DAQ on line reference manual to see the proper parameter to the ScanStart function that represents one of the two timebases above.

Hope this helps.

It is totaly right, I had a bad version of the NI-DAQ reference manual !
