3-41. AC Power Amplitude Accuracy (High Voltage)
The AC Power Amplitude Accuracy (High Voltage) test checks the current outputs at the
AUX terminals in the presence of a high voltage. Use the 5790A, A40 and A40A shunts,
and the shunt adapter, as described in the 5790A Operator Manual. Table 3-27 shows the
test points.

3-42. AC Power Amplitude Accuracy (High Current)
The AC Power Amplitude Accuracy (High Current) test checks the voltage outputs at the
NORMAL terminals in the presence of a high current. Apply a short to the AUX
terminals to provide a low-impedance path for current. Table 3-28 shows the test points.
