7-28. AC Voltage Harmonic Amplitude Accuracy (AUX)
Note
This verification test is optional. It is not necessary to guarantee the full
calibration of the instrument. However, it may be useful when
troubleshooting an instrument when other functions and/or parameters are
incorrect.
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.

7-29. DC Voltage Offset Accuracy
Note
This verification test is optional. It is not necessary to guarantee the full
calibration of the instrument. However, it may be useful when
troubleshooting an instrument when other functions and/or parameters are
incorrect.
The DC Voltage Offset Accuracy test the accuracy of the dc offset function for an ac
sinewave output on the NORMAL terminals.
