Source to
select the desired source, or rotate the multi-function knob to select a desired
source, then press down the knob to select it. You can also press Source
continuously to select the trigger source or enable the touch screen to tap the
desired trigger source and select it.
Analog channels (CH1-CH4), digital channels (D0-D15), EXT (external trigger), or AC
Line can all be selected as the trigger source.
Analog channel input:
Signals input from analog channels CH1-CH4 can all be used as trigger sources. No
matter whether the channel selected is enabled, the channel can work normally.
Digital channel input:
Signals input from digital channels D0-D15 can all be used as trigger sources. No
matter whether the channel selected is enabled, the channel can work normally.
External trigger input:
The external trigger source can be used to trigger on the fifth channel while all the
other four channels are acquiring data. The trigger signal (e.g. external clock or
signal of the circuit under test) will be connected to EXT trigger source via the
external trigger input terminal [EXT TRIG] connector. You can set the trigger
conditions within the range of the trigger level (from 8 V to +8 V).
AC line input:
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 triggering the waveform output from the transformer of a transformer
substation. It is mainly used in related measurements of the power industry.
