Operating the horizontal axis
TIME/DIV
Sets the sweep rate per scale (approximately 9 mm). The setting range is
5 ns to 50 s/div in 1-2-5 sequence. When pressing the TIME/DIV knob
if FFT is not selected in Math, either 1-2-5 sequence or 1-10-100
sequence are set.
The waveform is expanded or reduced based on the screen center. (See
the figure below.) The operation varies depending on the delay setting.
When trigger delay is zero
Trigger point does not change
DELAY
Sets the position of the trigger point in the horizontal direction.
The Delay time is a time interval from the trigger point to the screen
center as the zero point. When pressing the knob, the COARSE setting
(COARSE) is then selected.
Note that the setting range of the delay time varies depending on the
sweep rate and memory length setting. (See Section 2.)
Observe waveform 1 ms after
trigger is generated.

ZERO DELAY
Sets the trigger delay time to zero.
The trigger point comes to the screen center when zero.
