When the trigger mode is Normal or Single, click or tap Force in the trigger setting
interface to generate a trigger signal forcibly. You can also press the front-panel
to generate a trigger signal forcibly.
8.4 Trigger Coupling
Trigger coupling decides which kind of components will be transmitted to the trigger
module. Please distinguish it from channel coupling (
Channel Coupling
). This function
is available only when the trigger type is Edge and the trigger source is an analog
channel.
In the "Trigger" menu, click or tap the drop-down button of Coupling to select the
desired coupling mode (by default, it is DC).
• DC: allows DC and AC components to pass the trigger circuitry.
• AC: blocks the DC components and attenuates the signals.
• LFR: blocks the DC components and rejects the low-frequency components.
• HFR: rejects the high frequency components.
TIP
When "AC" or "LFR" is selected as the coupling mode, no trigger level lines and trigger icons
are displayed. When you adjust the trigger level, you can only see the changes of the trigger
level values in the trigger information label at the top of the screen.
8.5 Trigger Holdoff
Trigger holdoff can be used to stably trigger on complex repetitive waveforms that
have multiple edges or other events between waveform repetitions (such as pulse
series). Holdoff time indicates the time that the oscilloscope waits for re-arming the
trigger module after generating a correct trigger. The oscilloscope will not trigger
even if the trigger condition is met during the holdoff time and will only re-arm the
trigger module after the holdoff time expires.
For example, to stably trigger the repetitive pulse series as shown in the figure below,
the holdoff time should be set to a value that is greater than t1 and smaller than t2.
