Mark Description:

Mark represents position of current waveform
view window in RAM
Mark position of trigger point in RAM.
Mark position of trigger point in current
waveform view window.
Display horizontal time base (or main time
base), namely, s/div.
Trigger horizontal distance of position by
comparing with middle point of view window.
Term explanation:
Y-T mode: Y axle refers to voltage and X axle
refers to time quantum under this mode.
X-Y mode: X axle refers to CH1 voltage and Y axle
refers to CH2 voltage under this mode.
Slow scanning mode: Instrument will enter into
slow scanning sampling mode when setting
horizontal time base control to 100ms/div or less. It
is suggested to set channel coupling to DC when
observing low-frequency signal by applying for
slow scanning mode.
s-div: Time base control can expand or compress
waveform for horizontal scale (or time base) unit if
stopping waveform sampling (by using RUN/STOP
key).
