TRIGGER
TRIG_MODE | TRMD
Command /Query
DESCRIPTION
The TRIG_MODE command selects the
trigger sweep mode.
The TRIG_MODE? query returns the current
trigger sweep mode.
COMMAND SYNTAX
TRIG_MODE <mode>
<mode>:= {AUTO,NORM,SINGLE,STOP}
• AUTO — When AUTO sweep mode is
selected, the oscilloscope begins to search for
the trigger signal that meets the conditions.
If the trigger signal is satisfied, the running
state on the top left corner of the user interface
shows Trig'd, and the interface shows stable
waveform.
Otherwise, the running state always shows
Auto, and the interface shows unstable
waveform.
• NORM — When NORMAL sweep mode is
selected, the oscilloscope enters the wait
trigger state and begins to search for trigger
signals that meet the conditions.
If the trigger signal is satisfied, the running
state shows Trig'd, and the interface shows
stable waveform.
Otherwise, the running state shows Ready, and
the interface displays the last triggered
waveform (previous trigger) or does not
display the waveform (no previous trigger).
• SINGLE — When SINGLE sweep mode is
selected, the backlight of SINGLE key lights
up, the oscilloscope enters the waiting trigger
state and begins to search for the trigger signal
that meets the conditions.
If the trigger signal is satisfied, the running
state shows Trig'd, and the interface shows
stable waveform. Then, the oscilloscope stops
scanning, the RUN/STOP key is red light, and
the running status shows Stop.
