Trigger Source
Press MENU Source in the trigger control area (TRIGGER) at the front panel to
select the desired trigger source. Siganls input from CH1/CH2 and the [EXT TRIG]
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 input of the channel selected is enabled, the channel
can work normally.
External trigger input:
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. The trigger signal
(such as external clock and signal of the circuit to be tested) will be connected to
EXT trigger source via the [EXT TRIG] connector. You can set the trigger condition
within the range of trigger level (-4 V to +4 V).
AC line:
The trigger signal is obtained from the AC power input of the oscilloscope. This kind
of signal source can be used to display the relationship between signal (such as
illuminating device) and power (power supply device). For example, to stably trigger
the waveform output from the transformer of a transformer substation, which is
mainly used in related measurement of the power industry.
