In which version of DAQmx can I find AI.EnhancedAliasRejectionEnable property?

[benbol]

I have the NI PXI 4472B. I work at the acquisition frequency of 1024Hz. I have seen (in Dynamic Signal Acquisition Help, chapter 'Low-Frequency Alias Rejection') that between 1 kS/s and 25.6 kS/s, the anti-aliasing filters of DSA device AI channels may not completely reject all out-of-band signals. To resolve this problem, one way is to enable low-frequency alias rejection with the AI.EnhancedAliasRejectionEnable property.  

I have the DAQmx 7.5 version, and I did not find it. It should be on the node property of DAQ Create Channel. So, I would like to know which version of DAQmx has this property.

Thanks a lot,

ben

Bonjour,

Vous trouverez ci-joint l'endroit où trouver la propriété "AI.EnhancedAliasRejectionEnable" dans la classe DAQmx Channel (fait avec NI-DAQmx 7.4). Attention, cette propriété n'apparaît que si le matériel le supporte.
