4-29. Setting a Dual AC Voltage Output
Note
Tie the terminals NORMAL LO and AUX LO together at the UUT or at the
5520A, via the “LO”s softkey selection “tied.”
The calibrator produces a dual ac voltage output by sourcing one ac voltage on the
NORMAL outputs and a second on the AUX terminals.
Complete the following procedure to set a dual ac voltage output. If you make an entry
error, press Gone or more times to clear the display, then reenter the value.
Caution
Verify the applied voltage to the UUT does not exceed the
rating of the UUT insulation and the interconnecting wiring.
1. Press R to clear any output from the 5520A.
2. Connect the UUT as described earlier in this chapter under “Connecting the
Calibrator to a UUT.”
3. Set the UUT to measure dual ac voltage on the desired range.
4. Press the numeric keys and decimal point key to enter the desired voltage output at
the NORMAL terminals (maximum six numeric keys). For example, 123.456.
5. Press a multiplier key, if necessary. For example, press c.
6. Press V.
7. The Control Display now shows the amplitude of your voltage entry. For example,
123.456 mV (below).

Note
The AUX output is limited to 3.3 V rms for sine waves, 6.6 V p-p for square
waves, 9.3 V p-p for triangle and truncated sine waves.
8. Press the numeric keys and decimal point key to enter the desired voltage output at
the AUX terminals (maximum six numeric keys). For example, 234.567.
9. Press a multiplier key, if necessary. For example, press c.
10. Press V.
11. The Control Display now shows the amplitude of your entries for the NORMAL
terminals (upper reading) and AUX terminals (lower reading) (below is typical).
