hi
i am trying to creat a
digital pluse of user defined high and low pluse time, then i aquired
this signal back via analog input channel of DAQ ni USB 6008.
it
is giving me problem when i set the PULSE HIGH TIME to 1000ms and PULSE
LOW TIME to 1000ms. it some time shows randomly nothing or some time
continusly high pulse or low, but not exactly 1 second high or 1
second low all the time.
my first question is that is it the
right approach to creat a digital pulse or there is some other
efficient way to create such pulse?
second why it is skipping a
cycle durring the aquasition, because when i connect the digital output
to osciliscope it seems to be OK but when i aquired the same pulse back in the vi it works fine for like 10 cycles and then shows some kind of noise for 2 to 3 cycles repeatedly and then again back to normal transitions?
plz have a look on my vi,i am posting the vi for some good suggestions?
it really makes me worried why it is not working as expected.
thanks
