NI 5402/5406 Calibration Procedure
Adjusting the Sine Wave Flatness Correction
Complete this procedure to adjust the sine wave flatness correction of the
NI 5402/5406. In this procedure, you compare the signal generator’s power
level output during the generation of sine waves of various frequencies to
determine the flatness of the sine wave.
1.
Connect the NI 5402/5406 CH 0 front panel connector to a power
meter.
2.
Open an NI-FGEN external calibration session by calling the niFgen
Init Ext Cal VI.
3.
Initialize flatness calibration by calling the niFgen Initialize Flatness
Calibration VI.
