Hello,
I am quite new to the DAQ, so my question might sound very basic but I could not figure out the answer by myself. My main problem is related with how the trigger works because I could not understand the concept.
I have a DAQ USB 6003 and I will use Matlab ToolBox to control it. For my experimental system I need to use 2 analog ouputs and 1 analog input, and I want to trigger the output voltage to a constant DC value at given time intervals, wait a specific time while holding the output voltages and read the analog input.
My questions are:
1. If I select PFI0 as a source trigger and I want to start it at the rising edge of a pulse signal generated by one of the channels of my DAQ, is this considered Hardware or Software trigger type?
2. Which channel type should be used to create the pulse signal and drive the trigger? Analog or Digital? Is there any channel specifically designed to generate this type of waveform (at a given frequency and duty cycle)?
3. Can I use the same channel simultaneously, for instance PFI0, to trigger on a rising edge the analog outputs and on a a falling edge the analog input? Or should I have two different trigger sources? Or even a third scenario, where I just use a wait function after the rising edge trigger?
Thank you for any help you can give me.
