what is the switching time (delay) between analog input channels for WSN 3202?

[nurlaila]

Hi, I would like to know the switching time between the analog input channels for WSN 3202.

Since it is a multisample device, i want to know the amount of time delay between those channels so i can manipulate the delay to simultaneously sample the channels.

Hi nurlaila,

The 3202 uses a multiplexer for the analog inputs so it cannot perform true simultaneous sampling but it can do near simultaneous samples. What are you trying to sample and how fast of a settling time do you need? There is not a direct way to change the settling time as with DAQmx devices. However it can be indirectly effected by the settings you chose for the device. 

Cheers,

Hi Brian,

I understand that the switching time between the channels is too small, but is it measureable? I just want to know the time delay.

Thanks.
