Trigger Source
Press MENU  Source in the trigger control area (TRIGGER) at the front panel to
select the desired trigger source. Signals input from CH1/CH2, the [EXT TRIG]
connector or [LOGIC D0-D15] connector as well as the AC Line can all be used as
trigger source.
Analog channel input:
Signals input from analog channels CH1 and CH2 can all be used as the trigger
source. No matter whether the channel selected is enabled, the channel can work
normally.
Digital channel input:
Signal input from any digital channel of D0-D15 can all be used as the trigger source.
No matter whether the channel selected is enabled, the channel can work normally.
External trigger input:
Signals (such as external clock and signal of the circuit to be tested) input from the
[EXT TRIG] connector can be used as the trigger source. When this type of trigger
source is selected, you can set the trigger level within -4 V to +4 V by rotating
TRIGGER
LEVEL.
External trigger source can be used to connect external trigger signal to the [EXT
TRIG] channel when both of the two channels are sampling data.
AC line:
The trigger signal is obtained from the AC power input of the oscilloscope. AC trigger
is usually used to measure signals relevant to the AC power frequency. For example,
stably trigger the waveform output from the transformer of a transformer substation;
it is mainly used in related measurements of the power industry.
