bar and stable waveform is displayed. Otherwise, “WAIT” is displayed and the
waveform of the last trigger (there is a last trigger) or no waveform (there is not a
last trigger) is displayed.
Single:
When this mode is selected, the backlight of SINGLE turns on. The oscilloscope
enters the wait-for-trigger state and starts searching for trigger signals that meet the
specified condition. If trigger signals that meets the specified condition are found,
“T’D” is displayed in the running status bar and stable waveform is displayed. Then,
the oscilloscope stops sweeping, the backlight of RUN/STOP turns on and “STOP”
is displayed in the running status bar. Otherwise, “WAIT” is displayed in the running
status bar and no waveform is displayed.
Note: In this mode, pressing FORCE can generate a trigger signal forcefully.
Trigger Coupling
Trigger coupling decides which kind of components will be transmitted to the trigger
module. Please distinguish it from “Channel Coupling”.
DC: allow DC and AC components into the trigger path.
AC: block all the DC components and attenuate signals lower than 75 Hz.
LF Reject: block the DC components and reject the low frequency components
(lower than 75 kHz).
HF Reject: reject the high frequency components (higher than 75 kHz).
Press MENU Setting Coupling in the trigger control area (TRIGGER) at the
front panel to select the desired coupling type (the default is DC).
Note: Trigger coupling is only valid in edge trigger.
