Level Selection and Setting
After the trigger condition setting is completed, you need to adjust the trigger level
to correctly trigger the signal and obtain a stable waveform.
Click or tap the Level A/Level B input field to set the level A/level B with the pop-up
numeric keypad. You can also use the trigger level knob or use the corresponding
multipurpose knob to adjust level A/level B. When
Linkage is ticked, the upper limit
and lower limit values change at the same time. The difference between upper and
lower limit remains unchanged. For details, refer to descriptions in
Trigger Level
. The
current trigger level is displayed in the trigger information label at the top of the
screen.
TIP
Press the trigger level knob to switch between three modes: "only adjust Level A", "only adjust
Level B", and "adjust Level A and Level B at the same time".
