Hi,
I am using NI USB 6211 card in my application for analogue voltage measurements. I am using external pulse generator of 20 kHz to trigger the circuit. It seems that there is a DEDICATED square pulse generator built in to the card. It is a great help if someone could help me to make use of that dedicated pulse generator (Frequency Generator module ) in order for me to generate 20 kHz square pulse which does not interfere with the analogue voltage measurements. It is my understanding that use of ordinary digital output may not help me.
Thank you in advance
Wella

Perhaps this might better be posed on the National Instruments forum: http://forums.ni.com/
