Trigger Source

Press MENU  Source in the trigger control area (TRIGGER) at the front panel to

select the desired trigger source. Signals input from the analog channels CH1-CH4

and the [EXT TRIG] connector as well as the AC Line can all be used as the trigger

source.

Analog channel input:

Signals input from analog channels CH1-CH4 can all be used as the trigger source.

No matter whether the input from the channel selected is displayed, the channel can

work normally.

External trigger input:

External trigger can be used to trigger on the fifth channel at the same time when all

the four channels are acquiring data. The trigger signal (e.g. external clock, signal of

the circuit to be tested) will be connected to EXT or EXT/5 trigger source via the

[EXT TRIG] connector.

Trigger signals can use the EXT trigger source directly. You can use the EXT trigger

source to set the trigger conditions within the range of the trigger level from – 0.6 V

to + 0.6 V. When EXT/5 trigger source is used, the range of the external trigger level

can be extended to from – 3 V to + 3 V to make the oscilloscope to trigger when

relatively bigger signals occurred.

AC Line:

The trigger signals are obtained from the AC power input of the oscilloscope. This

kind of signals 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.
