10. Trigger Source
Display the trigger source currently selected (CH1-CH4 or AC
Line). Different labels are displayed when different trigger
sources are selected and the color of the trigger parameter
area will change accordingly.
For example:
denotes that CH1 is selected as the trigger
source.
11. Trigger Level
at the right of the screen is the trigger level label and
the trigger level value is displayed at the upper-right
corner of the screen.
When using TRIGGER
LEVEL to modify the trigger
level, the trigger level value will change with the up and
down of
.
Note: in slope trigger, runt trigger and windows trigger, there
are two trigger level labels (
and ).
12. CH1 Vertical Scale
Display the voltage value per grid of CH1 waveform
vertically.
Use VIRTICAL
SCALE to modify this parameter.
The following labels will be displayed according to the
current channel setting: channel coupling (e.g.
) and
bandwidth limit (e.g.
).
13. CH2 Vertical Scale
Display the voltage value per grid of CH2 waveform
vertically.
Use VIRTICAL
SCALE
to modify this parameter.
The following labels will be displayed according to the
current channel setting: channel coupling (e.g.
) and
bandwidth limit (e.g.
).
14. CH3 Vertical Scale
Display the voltage value per grid of CH3 waveform
vertically.
Use VIRTICAL
SCALE
to modify this parameter.
The following labels will be displayed according to the
current channel setting: channel coupling (e.g.
) and
