User Manual

The axis of the vertical scale is GND level. The readout on the top right cornerˈ

which unit is sec, show us the horizontal position. “M” Mean main time base, “W”

mean window time base.. It is also a arrow on the scale top to show the vertical

position.

Ŷ Window Zone: Using “Window Zone” to define one wave sect, it is useful to reap

the details. The Window time base setting cannot be set slower than the Main time

base setting.

Ŷ Window: Expand the window to cover the whole screen.

2.7.1 Horizontal control knob

You can use the horizontal controls to change the horizontal scale and position

of waveforms. The horizontal position readout shows the time represented by the

center of the screen, using the time of the trigger as zero. Changing the horizontal

scale causes the waveform to expand or contract around the screen center.

Ŷ Horizontal “POSITION” knob

1. Adjust the horizontal position of all channels and math waveforms (the position of

the trigger relative to the center of the screen). The resolution of this control varies

with the time base setting.

2. When you press the horizontal “POSITION” Knob, you can set the horizontal

position to zero.

Ŷ“S/div” knob

1. Using to change the horizontal time scale to magnify or compress the waveform. If

waveform acquisition is stopped (using the RUN/STOP or SINGLE button), turn the

S/div knob to expand or compress the waveform.

2. Select the horizontal time/div (scale factor) for the main or the window time base.

When Window Zone is enabled, it changes the width of the window zone by

changing the window time base.

Ŷ Display scan mode˖

When the SEC/DIV control is set to100 ms/div or slower and the trigger mode
