amplitude signals. You can also toggle the trigger off and on by pressing ??.
•
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
The V/DIV Menu
The V/DIV menu, shown below, sets the number of volts denoted by each division on the
oscilloscope. This menu provides alternative methods for changing the output amplitude
that may be more convenient for certain oscilloscope applications. To access the V/DIV
menu, press V/DIV from the Volt menu.

Each item in the V/DIV menu is described below.
•
V/div
Changes the scale of the output display by changing the number of volts that
are represented by each division. The available settings, shown in the figure above,
are provided in 1-2-5 step increments. Press the softkey under
UP
to increase the
volts per division. Press the softkey under
DOWN
to decrease the volts per division.
•
# DIV
Specifies the number of divisions that establish the peak-to-peak value of the
waveform. The value can be adjusted from one to eight divisions. The amount
denoted by each division is displayed in the V/div field. Press the softkey under UP
to increase the signal’s height, and press the softkey under DOWN to decrease it.
Shortcuts to Set the Voltage Amplitude
The
X
and
D
keys step the voltages through cardinal point values of an
oscilloscope in a 1-2-5 step sequence. For example, if the voltage is 40 mV, then pressing
X
increases the voltage to the nearest cardinal point, which is 50 mV. Pressing
D
decreases the voltage to the nearest cardinal point, which is 20 mV.
Amplitude Calibration Procedure for an Oscillosope
This example procedure describes how to use the Volt menu to calibrate the
oscilloscope’s amplitude gain. During calibration, you will need to set different voltages
and verify that the gain matches the graticule lines on the oscilloscope according to the
specifications for your particular oscilloscope. See your oscilloscope manual for the
recommended calibration settings and appropriate gain values.
Before you start this procedure, verify that you are running the oscilloscope option in
Volt mode. If you are, the Control Display shows the following menu.
