I also have some problems with setting the time base with the adc200.vi example from pico.
I have an adc 212 card, that works well with the original picoscope software (timebase and everything are ok).
When I try to run the example vi. in labview8, I get a wrong timebase, that is 333 ns/sample for tha "0" input value.
With this sampling rate I get 333 ms that corespond to a real 0.5 ms with picoscope.
What do I do wrong? Or could be something with the pico driver? (I downloaded it from picotech aprox. one month ago).
