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 corresponding multipurpose knob to adjust
level A/level B or use the trigger level knob to adjust the level (the focus of the trigger
level knob is the last modified level). 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.
8.7.11 Setup/Hold Trigger
In setup&hold trigger, you need to set the clock source and data source. The setup
time starts when the data signal passes the trigger level and ends at the coming of
the specified clock edge; the hold time starts at the coming of the specified clock
edge and ends when the data signal crosses the trigger level again, as shown in the
figure below. The oscilloscope triggers when the setup time or hold time is smaller
than the preset time.
