Calibrate the Voltage Amplitude on an Oscilloscope
To calibrate oscilloscope voltage gain, apply a low frequency square wave signal and
adjust its gain to the height specified for different voltage levels, designated by the
graticule line divisions on the oscilloscope. Apply the signal from the 5502A in Volt
mode. The voltages that you must use for calibration, and the graticule line divisions that
are necessary to be matched, can be different for different oscilloscopes. These are
specified in your service manual for your oscilloscope.
The Volt Function
The Voltage gain is calibrated with the volt function. This function is accessed through
the Volt menu, which shows when you start the SCOPE option, or when you push the
softkey below MODE to scroll through the oscilloscope calibration menus, see below.

Each menu item is described below:
•
OUTPUT @ SCOPE Shows the location of the signal output. If the signal does not
show on the oscilloscope, push

. To disconnect the signal, push

.
•
DC <-> AC Toggles between a dc and ac signal. Push the softkey from the ac signal
to make the dc equivalent output.
•
SCOPE Z Toggles the output impedance setting of the Calibrator between 1 M
Ω
and
50
Ω
.
•
V/DIV MENU Opens the voltage scaling menu, which lets you select the scale of
the signal in volts per division. This menu is shown below in the “The V/DIV Menu”
section.
•
MODE Shows you are in volt mode. Use the softkey to change modes and open its
menus for the other four oscilloscope calibration modes.
