Calibrating The Voltage Amplitude On An Oscilloscope; The Volt Function - Fluke 5500A Operator's Manual

8-93. Calibrating the Voltage Amplitude on an Oscilloscope

The oscilloscope voltage gain is calibrated by applying a low frequency square wave
signal and adjusting its gain to meet the height specified for different voltage levels,
designated by the graticule line divisions on the oscilloscope. The signal is applied from
the 5520A in Volt mode. The specific voltages that you should use for calibration, and
the graticule line divisions that need to be matched, vary for different oscilloscopes and
are specified in your oscilloscope's service manual.

8-94. The Volt Function

The Voltage gain is calibrated using the Volt function. This function is accessed through
the Volt menu, which appears when you start the SCOPE option, or when you press the
softkey under MODE to scroll through the oscilloscope calibration menus.
Each menu item is described below:
OUTPUT @ SCOPE Indicates the location of the signal output. If the signal does
not appear on the oscilloscope, press
DC <-> AC Toggles between a dc and ac signal. Pressing the softkey from the ac
signal produces the dc equivalent output.
SCOPE Z Toggles the calibrator's output impedance setting between 1 M and
50 .
V/DIV MENU Opens the voltage scaling menu, which lets you select the scale of
the signal in volts per division. This menu is described below in detail, under "The
V/DIV Menu."
MODE Indicates you are in Volt mode. Use the softkey to change modes and open
the corresponding menus for the other four oscilloscope calibration modes.
