Ac Voltage Harmonic Amplitude Accuracy (Aux); Dc Voltage Offset Accuracy - Fluke 5500A Service Manual

3-48. AC Voltage Harmonic Amplitude Accuracy (AUX)

The AC Voltage Harmonic Amplitude Accuracy (AUX) tests the accuracy of the 50th
harmonic from the AUX terminals. For this test, set the 5500A output to sinewave. Table
3-35 shows the test points.

3-49. DC Voltage Offset Accuracy

The DC Voltage Offset Accuracy test the accuracy of the dc offset function for an ac
sinewave output on the NORMAL terminals. Table 3-36 shows the test points.
