Hi All,
Sorry I already posted one message in "counter/timer" column. But I'm not sure if I posted in a right place, and here is the message. (Please delete it if not right):

Hi all,
I'm new to LV, and I met with some problems when I wanted to generate several pulses. I wanna use 3 channels to output 3 different pulses, and the accuracy should be microsecond(us) magnitude. The DAQ board I'm using is PCIe-6251 board, on which there are two 32-bit 80MHz counter/timers. So can I generate 3 different pulses using these 2 counters? And do I have to use counters to generate a microsecond magnitude pulse?
Another question is, I made a prgramme to do the analog input. And it runs at about 20K Hz. The source of the AI clock was set as onboard clock. Although the specification told me that the AI is 16 bits, 1.25MS/s, I didnt see difference when I set the frequecy from 20k to 1M Hz(which is 20K always). Is it the only way using an external reference clock?
I'm using LV 8.5, under Windows XP OS. Thank you.
Best wishes
Bo
