5.8 Zooming in Vertical Direction
(For High-Speed Isolation/High-Speed/High-Resolution, High-Voltage, Isolation/High-
Resolution, Isolation/Logic Input Modules)
≡ For a description of this function, refer to page 1-5. ≡
Function
The displayed waveform can be enlarged/reduced in vertical direction. It is useful when you
wish to change the vertical axis setting after displaying waveforms using Single Start/Log Start
(refer to page 4-6).
Selecting the trace to zoom
Select one waveform from CH1 to CH16.
However, if the selected waveform display is OFF, it cannot be zoomed.
Zoom factor
The following zoom factors are available.
× 0.1, × 0.2, × 0.25, × 0.4, × 0.5, × 0.75, × 0.8, × 1, × 1.14, × 1.5, × 1.6, × 1.77, × 2, × 2.28, × 2.66, × 3.2,
× 4, × 5, × 8, × 10, × 12.5, × 16, × 20, × 25, × 40, × 50 and × 100.
Zoom position
Zooms with the center at the vertical position.
1div=1V 1div=500mV
When “V Zoom” is switched from “x1” to “x2”
Operating Procedure
1. Press one of the keys CH1 to CH16 to select the channel to zoom and turn the display ON.
2. Press the “ V Zoom/Offset ” soft key to set jog shuttle action to “ V Zoom .”
3. Turn the jog shuttle to set the desired zoom factor.

Note
• If the item being controlled by the jog shuttle is “V Zoom,” pressing the
RESET
key will set the zoom
factor to x1.
• 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”).
