MENU
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. You can set the trigger conditions within the range of the
trigger level from -0.8 V to +0.8 V.
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.
