Auto?
(flashing) — the trigger condition is not found (after the pre-trigger buffer
has filled), and forced triggers and acquisitions are occurring.
•
Auto
(not flashing) — the trigger condition is found (or the pre-trigger buffer is
being filled).
In the
Normal
trigger mode, the trigger indicator can show:
•
Trig'd?
(flashing) — the trigger condition is not found (after the pre-trigger buffer
has filled), and no acquisitions are occurring.
•
Trig'd
(not flashing) — trigger condition is found (or pre-trigger buffer is being
filled).
When the oscilloscope is not running, the trigger indicator area shows
Stop
.
When to Use Auto
Trigger Mode
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.
When to Use
Normal Trigger
Mode
The
Normal
trigger mode is appropriate when:
• You only want to acquire specific events specified by the trigger settings.
• Triggering on an infrequent signal from a serial bus (for example, I2C, SPI, CAN,
LIN, etc.) or another signal that arrives in bursts. The
Normal
trigger mode lets
you stabilize the display by preventing the oscilloscope from auto-triggering.
• 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 don't 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).
