Verifying the Sine Wave Flatness Correction
Accuracy
This test verifies the Sine Wave Flatness Correction Accuracy of the
NI 5402/5406. In this procedure, you will compare the signal generator’s
output power level during the generation of sine waves of various
frequencies to the output power level measured during the generation of a
50 kHz sine wave. The following figure shows the programming flow for
this test:
