Hi guys,
I'm having the following problem with Labview NXG and cDAQ9189; I'm acquiring analog and digital input at 1000 Hz, analog for 300 s, digital for 5 s, 1 s pretrigger.
I've done 10 tests and everything worked out fine but in the past few days I've been experiencing some problems: data acquisition is shifted (lagging) around 30 s (both digital and analog) from trigger signal so i'm missing pieces; I can't figure out what's happening.
Obviously this happens only when I run real test, if I run a "blank" test everything seems fine.
I'm attacching correct (blank test) and uncorrect (real test) behaviour.
thanks
