Hi Federico,
As it has been said in your other post, you cannot use analog trigger if your module does not support it.
Although there is a little workaround to use analog triggering with unsupported modules, you would still need another module in the same task that does support it: Acquisition with Analog Triggering on a CompactDAQ - NI
Otherwise, your only option is to create a pseudo-trigger programmatically-- start data acquisition and use the values only when the signal surpasses the desired threshold.
Best,
Fort
