3-46. AC Voltage Amplitude Accuracy, Squarewave (AUX)
The AC Voltage Amplitude Accuracy, Squarewave (AUX) test checks the amplitude
accuracy at the AUX terminals. For this test, use the Fluke 5790A. Refer to the 5790A
Operator Manual for operating instructions and connections. For squarewaves, the
measured value (in rms) should be exactly 1/2 the nominal value in peak-to-peak. Table
3-33 shows the test points.
