7.
The measured frequency should converge on the desired frequency.
If the measured frequency does not converge on the desired frequency
within 16 iterations, a problem may exist with your measurement
device or the NI 5402/5406.

Abort waveform generation by calling the niFgen Abort
Generation VI.
b.
Adjust the oscillator frequency by calling the niFgen Cal Adjust
