• Normal: In this trigger mode, triggers and acquisitions only occur when the
specified trigger conditions ar
e found. This trigger mode can be used when the
signal is at a low repetition rate, when you only want to acquire specific events
specified by the trigger settings, or when you try to stabilize the display by
preventing the oscilloscope from auto-triggering.
• Single: In this trigger mode, a single trigger and acquisition only occur when the
specified trigger conditions are found, and then the oscilloscope stops. This
trigger mode can be used when you need to make a single acquisition of the
specified event and analyze the acquisition result. You can pan and zoom the
currently displayed waveform without subsequent waveform data overwriting
the current waveform. After a single trigger is initiated, the oscilloscope is in
"STOP" state.
In
Normal and Single trigger modes, you can click or tap the Force button in the
trigger menu or pr
ess the front-panel
key to force a trigger event.
8.4 Trigger Coupling
Trigger coupling determines what part of the signal is passed to the trigger circuit.
Please distinguish it from channel coupling (
To Specify 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
Coupling drop-down butt
on to select the
desired coupling mode (by default, it is DC).
• DC: allows DC and AC components t
o 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 select
ed 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.
