The ENTER key loads a newly entered output value shown on the Control Display into the
5520A, which appears on the Output Display. The new value can come from the numeric
keypad. If you press ENTER without identifying the units for the entry, in most cases the 5520A
keeps the units that were last used. This allows you, for example, to enter 1 mV, and then later
enter 10 to obtain 10 V. (The "V" units were saved from the last entry, but not the multiplier,
"m".) In the Error (edit) mode, ENTER with no value restores the output to the value of the
reference.

The SHIFT key selects alternate functions of the units keys and alternate multipliers of the
multiplier keys. These alternate selections are labeled with small letters in the upper left hand
corner of the keys.
X
Numeric Keypad
Used to enter the digits of the output amplitude and frequency. The proper sequence to enter a
value is to press the digits of the output value, a multiplier key (if necessary), an output units key,
then ENTER. For example, to obtain an output of 20 mV, you would press the following
sequence of keys: 2 0 c V. Press Oto enable the output. Pressing a digit key
once the entry field is full, and pressing the decimal point key more than once in a single number
will sound the beeper.
Y
I
The I (Polarity) key changes the polarity of the output for dc voltage or dc current functions.
Press the I key then E to toggle the output polarity.
Z
The SCOPE TRIG (Scope Trigger) BNC connector is used to trigger the oscilloscope during
oscilloscope calibration. This is active only when an oscilloscope option is installed.

The SCOPE OUT (Oscilloscope) BNC connector is used for outputs during oscilloscope
calibration. This is active only when an oscilloscope calibration option is installed.
