Why might calibration using the DSA Calibrate.vi work and NI-DAQ's Calibrate_DSA (deviceNumber, ND_SELF_CALIBRATE, 0.0) not work?

[JackMetcalfe]

When I call on the NI-DAQ function Calibrate_DSA(1, ND_SELF_CALIBRATE, 0.0) no error code is returned but subsequent measurements are terrible.

When I run a vi that calls on the DSA Calibrate.vi with a taskID of 1 indicating device 1 the accuracy is improved.

If LabVIEW is using the NI-DAQ API then it must be possible to get it to work.

Any suggestions would be appreciated,
Jack

Just figured it out on my own but wanted to share in hopes others would find it useful or the help for the NI-DAQ function Calibrate_DSA would be improved in a future release.

After calling Calibrate_DSA the board must be initialized before being used via Init_DA_Brds().

If anyone feels these conclusions are even partly in error please let me know.

Also, if anyone agrees that this is the case let me know why?

Thanks,
Jack
