4-23. 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 VOLTAGE menu.

The following describes each item in the V/DIV menu:
•
V/div Changes the number of volts per division in the Output Display so that the
values selected correspond to the oscilloscope's input sensitivity (VOLTS/DIV.) 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.
4-24. Shortcuts for Setting the Voltage Amplitude
The u and a 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, pressing
u increases the voltage to the nearest cardinal point, which is 50 mV. Pressing a
decreases the voltage to the nearest cardinal point, which is 20 mV.
