The sampling rate setting in DAQmxCfgSampClkTiming

[David_Lin]

Hi,

I would like to set up the sampling rate of PCI-6251with DAQmxCfgSampClkTiming(*taskHandle,"",SampRate,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,samplesPerChan) for multi AI channels. The 6251 manual says the highest sampling rate for signle channel is 1.25M and 1M for multi-channel. Does that mean I have to set the SampRate to be 1M or it has to be divided by the number of channels (500K if I have two analog inputs?)?

Thanks

David.

Hi David!  look  here 
It seems that you have to divide!

Hello David,

Graziano is right, it's 1MS/s divided by the number of channels in the scan list.
