Adjusting the Oscillator Frequency
Complete this procedure to adjust the oscillator frequency of the
NI 5402/5406. In this procedure, you generate a 10 MHz sine wave,
iteratively measure the sine wave frequency with a frequency counter, and
adjust the oscillator frequency until the measured frequencies fall within
the desired tolerance 4.5 ppm.
1.
Connect the NI 5402/5406 CH 0 front panel connector to the frequency
counter.
2.
Open an NI-FGEN external calibration session by calling the niFgen
Init Ext Cal VI.
3.
Initialize oscillator frequency calibration by calling the niFgen
Initialize Oscillator Frequency Calibration VI.
