Resolution, Isolation Modules)

Function
The V/div (voltage axis sensitivity) setting is used to adjust the amplitude of the displayed
waveform so that the waveform can be observed easily. The V/div setting is made by setting
the voltage value per division on the screen grid. Setting is in 1-2-5 steps (1V/div
→
2V/div
→
5V/div).
V/div setting range
The setting range varies depending on the input module as shown below.
Input module
Setting range
High-Speed Isolation Module
5mV/div to 20V/div
High-Speed Module
5mV/div to 20V/div
High-Resolution, High-Voltage, Isolation Module
50mV/div to 200V/div
High-Resolution, Isolation Module
5mV/div to 20V/div
* The above values are given for a probe attenuation of 1:1. They will be 10 times the value shown when it is
10:1, 100 times the value shown when it is 100:1, and 1000 times the value shown when it is 1000:1.
V/div display
If the V/DIV knob is turned while the waveform acquisition is stopped, the top section displays
the V/div corresponding to the displayed waveform and the bottom section displays the changed
V/div. The changed V/div value becomes valid on the next start.

Operating Procedure
1.
Press one of the keys
CH1
to
CH16
to select the desired channel. To select the optional 32-
bit extended logic input (/N1), press the
SHIFT
key and then either the
CH1
key (LOGIC1)
or the
CH2
key (LOGIC2).
2.
Turn the
V/DIV
knob to set the desired value.
Note
• Rotating the
V/DIV
knob while acquisition is suspended has no affect on cursor and automatic
measurements, which continue to reflect the original V/div scale until acquisition is resumed.
• Certain screens allow you to use the jog or shuttle dial and
SELECT
key to select the channel(s) for V/
div setting. This feature is available (a) immediately after power ON, (b) immediately after
initialization or automatic setup, and (c) when you are reloading saved data. You can also produce one
of these screens by pressing the
ESC
key one or more times. Refer to page 5-14.
• The upper section of the V/div display (upper left of the screen) when zooming in the vertical direction
with “V Zoom,” is the V/div corresponding to the displayed waveform (V/div that is zoomed with “V
Zoom”). The lower section is the value being set with the V/div knob (V/div before zooming with “V
Zoom”).
