Chapter III Horizontal System

3.1 Horizontal control

(1) Horizontal control knob
Change the horizontal time-base scale through SCALE knob, changing of horizontal scale
can lead to expansion or shrink of waveforms relative to screen center. The horizontal
system can be controlled by the following panel buttons/knobs.
Change the horizontal position of waveform on the screen through POSITION, when the
horizontal position is changing, the position relative to the waveform trigger point will move
right and left.
(2) Horizontal menu button
Press HORI MENU to enter the horizontal menu function. (See table below)

3.2 Explanation of nouns

YT Mode：In this mode, the Y axis represents the amount of voltage, and the X axis
represents the amount of time.
XY Mode：In this mode, the X axis represents the CH1 voltage amount, and the Y axis
represents the CH2 voltage amount.
Scan Mode：When the horizontal time base control is set at 100ms/div or slower, the
instrument enters the slow scan sampling mode. When using the slow scan mode to
observe low frequency signals, it is recommended to set the channel coupling to DC.
SEV/DIV：Horizontal scale (time base) units, such as waveform sampling is stopped (using
the RUN/STOP button), and the time base control expands or compresses the waveform.
