Feature Front Panel Key/Softkey Location (see built-in help for more information)
Trigger mode [Trigger] > Mode
You can also configure the [Quick Action] key to toggle between the Auto and Normal trigger modes.
See "Configuring the [Quick Action] Key" on page 92.
Auto trigger mode [Trigger] > Mode, Auto
If the specified trigger conditions are not found, triggers are forced and acquisitions are made so that
signal activity is displayed on the oscilloscope. The Auto trigger mode is appropriate when:
• Checking DC signals or signals with unknown levels or activity.
• When trigger conditions occur often enough that forced triggers are unnecessary.
Normal trigger mode [Trigger] > Mode, Normal
Triggers and acquisitions only occur when the specified trigger conditions are found. The Normal
trigger mode is appropriate when:
• You only want to acquire specific events specified by the trigger settings.
• Making single-shot acquisitions with the [Single] key.
Often with single-shot acquisitions, you must initiate some action in the device under test, and
you do not want the oscilloscope to auto-trigger before that happens. Before initiating the action
in the circuit, wait for the trigger condition indicator Trig'd? to flash (this tells you the pre-trigger
buffer is filled).
Force trigger [Force]
When in the Normal trigger mode and no triggers are occurring, you can force a trigger to acquire
and display waveforms (which may show why triggers are not occurring).
Trigger coupling [Trigger] > Coupling (DC, AC, LF Reject, TV/Video)
NOTE: Trigger coupling is independent of channel coupling (see "Vertical Controls" on page 36).
Trigger noise reject
[Trigger] > Reject, Entry knob to select Noise Reject, push Entry knob to enable or disable
Trigger high frequency
reject
[Trigger] > Reject, Entry knob to select HF Reject, push Entry knob to enable or disable
Trigger holdoff [Trigger] > Holdoff
The correct holdoff setting is typically slightly less than one repetition of the waveform.
