Note
Voltage on the AUX output is limited to 3.3 V maximum.
9. 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.
10. Press I to select the polarity of the voltage (default is +).
11. Press a multiplier key, if necessary. For example, press c.
12. Press V.
13. The Control Display now shows the amplitude of your entries for the NORMAL
terminals (upper reading) and AUX terminals (lower reading) (see below).
123.4567 mV
234.567 mV
14. Press E. The calibrator clears your entry from the Control Display and copies
it into the Output Display (below is typical).
STBY
+123.4567 mV
+234.567 mV
15. Press O to activate the calibrator output.
A softkey labeled “LO”s appears on the Control Display.

• “LO”s (Low Potential Output Terminals) The front panel NORMAL LO and AUX
LO terminals must be tied together either at the UUT or at the 5500A. When the
front panel NORMAL LO and AUX LO terminals are tied at the UUT, select “open”
with the “LO”s softkey. If the NORMAL LO and AUX LO terminals are not tied at
the UUT, select “tied” with the “LO”s softkey. The default is tied.
