18 30 MHz oscilloscope
4.5. Trigger
(17) (21) SOURCE - Trigger source
Selection by pressing on the  key (17) or  (21):
The indicator corresponding to the selected source is lit.
Synchronization by channel CH1.
CH1 CH2 ALT LINE EXT
Synchronization by channel CH2.
CH1 CH2 ALT LINE EXT
Trigger source defined according to the display mode
CH1 CH2 ALT LINE EXT
Display mode: Trigger channel:
CH1 mode CH1
CH2 mode CH2
ALT mode Channel 1 synchronized with CH1
Channel 2 synchronized with CH2
CHOP mode same as ALT mode, since this mode is
forced.
ADD (light On) CH1
-CH2 (light On) CH2
Synchronization by the mains power supply frequency.
CH1 CH2 ALT LINE EXT
The coupling control is disabled. The phase may be adjusted
using the LEVEL control (13).
Synchronization by the external source connected to the BNC

plug (19).
(16) Automatic trigger of the timebase.
Traces visible even if there is no trigger event.
(13) LEVEL
Trigger level adjustment potentiometer.
The TRIG light is on when a trigger event is detected (timebase
activated).
(14) Trigger slope
Light On: trigger on rising slope
Light Off: trigger on falling slope
