I want to measure time from rising edge of CH1 to rising edge of CH2.
Front panel control using the Delay measurement works
-- Returns 512uSec, which is the expected value
Programming the delay measurement using NI Max is not working.
-- I am missing something when implementing the measurement.
-- The return value is always 1.024mSec (2x the expected result)
