NI 5402/5406 Calibration Procedure
a. Set the frequency by calling the niFgen Property Node and
selecting Standard Function Output»Frequency.
LabVIEW Block Diagram
b. Use the power meter to measure the power level output of the
NI 5402/5406. This value is the measured power of the generated
sine wave (dB).
c. Check to see whether the sine wave flatness error falls between the
high and low flatness error calibration test limits. Flatness error
can be determined by using the following calculation:
Sine Wave Flatness Error =
d. Repeat steps 10a through 10c for each frequency in Table 4.
11. Abort waveform generation by calling the niFgen Abort
Generation VI.
