Waveform Display Function

The selected trigger mode is “Normal”. After triggering, the
trigger state “Trig” appears.
The selected trigger mode is “Normal”. The trigger state is
“Trig?” if triggering is not performed.
Press the soft key [Stop] in the waveform display interface. The
trigger state “Stop” appears.
Vertical calibration
The voltage range and current range are subject to vertical calibration
(voltage/scale and current/scale). Press the soft key [Knob Func] and select
Volt Range or CURR Range. Rotate the knob to set the voltage or current range
of each interval.
Horizontal calibration
If the soft key [Knob Func] is pressed and “Time/div” is selected, you can rotate
the knob to adjust the horizontal scale (scanning speed). When the horizontal
(time/scale) setting is changed by rotating the knob, you can observe the
change of time/scale on the screen. During data collection, the sampling speed
can be changed by adjusting the horizontal calibration knob. After collection is
stopped, the collected data can be amplified by adjusting the horizontal
calibration knob.
Trigger delay
If the soft key [Knob Func] is pressed and “Trig Delay” is selected, you can
rotate the knob to adjust the trigger delay. In this case, if the knob is rotated, the
trigger point will move horizontally and the delay time will be displayed on the
screen. To change the delay time, move the trigger point ( ) horizontally and
set the distance between the trigger point and the horizontal center. The trigger
point moves along the top end of the display grid.
Trigger waveform
When the specified trigger conditions are satisfied, the trigger waveform will be
displayed. The triggering time is the trigger point, generally on the right of the
screen. When the trigger point is reached, the screen will display the waveform
from left to right over time. The user should set the following parameters before
using the trigger function.
⚫ Trigger mode
The trigger mode refers to the condition to update the contents on the
screen. It is divided into the Auto mode and Normal mode. In the Auto
mode, the displayed waveform will be updated when triggering occurs in
the suspension time; otherwise, the displayed waveform will be updated
automatically.
In the Normal mode, the displayed waveform will be updated in the case of
triggering and not updated in the case of no triggering.
⚫ Trigger source
The trigger source is used for generating trigger conditions. The user can
select the trigger source in the input signal of the input unit.
