dear all, I'm facing serious troubles in understanding whether it is possible to do the following thing with a NI-6251 USB.
I have two sensors and I want to turn on the second sensor only when a signal from the first sensor is above a given threshold; then I want to sample the output of the second sensor only when is turned on. So I need to manage three signals:
1. I need to acquire the triggering signal from the first sensor and when the signal is above a threshold
2. I need to ouput a high signal to turn on the second sensor
3. I need to acquire and logging the output of the second sensor
I would be very happy if someone could explain me if
1. it is possible to do it with a NI-6251 USB daq
2. how to do it (i'm gonna to use LabView)
thanks a lot
dave
