Table 2-13 Edge trigger function menu:
Option Setup Description
Type Edge
Edge trigger happens when a trigger input signal
crosses the trigger electric level at a rise edge or a
fall edge.
CH1
CH2
Triggers on a channel whether or not the waveform
is displayed
EXT
Does not display the trigger signal; the Ext option
uses the signal connected to the EXT TRIG front
panel BNC and allows a trigger level range of -12V
to + 12V
EXT/5
Same as Ext option, but attenuates the signal by a
factor of five, and allows a trigger level range of +6V
to -6V. This extends the trigger level range.
Signal
source
AC Line
This selection uses a signal derived from the power
line as the trigger source; trigger coupling is set to
DC and the trigger level to 0 volts.
Slope
Rise edge
Fall edge
Rise and fall
edge
Trigger the signal at the rising edge.
Trigger the signal at the falling edge.
Trigger the signal at the rising edge and the falling
edge.
Trigger
modes
Auto
Normal
Single
Automatic trigger can be implemented to finish
acquisition at the mode when no valid trigger exists.
Only valid triggered waveform is checked at the
mode. The waveform is acquired only when
satisfying the trigger condition.
Acquire a waveform when detecting a single trigger,
and then stop.
Setup
Skip to the trigger setup menu.
