Note: to select stable channel waveform as the trigger source to stabilize the
display.
Trigger Source
The 2-channel oscilloscope’s trigger source includes analog channels,
EXT, EXT/5
and AC Line. The 4-channel oscilloscope’s trigger source includes analog channels
and AC Line.
Press the Setup button on the front panel to enter the TRIGGER function menu;
press the Source softkey and then turn the Universal Knob to select the desired
trigger source.
The current trigger source is displayed at the upper right corner of the screen.
Select channel with signal input as trigger source to obtain stable trigger.
Analog channel input:
Signals input from analog channels can all be used as the trigger source.
External trigger input:
External trigger source can be used to connect external trigger signal to the EXT
TRIG channel when all of the four channels are sampling data. The trigger signal
(such as external clock and signal of the circuit to be tested) will be connected to
EXT and EXT/5 trigger source via the [EXT TRIG] connector. EXT/5 trigger source
attenuates the signal by a factor of 5. It extends the trigger level. You can set the
trigger condition within the range of trigger level (-8 div to +8 div).
AC line:
The trigger signal is 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, it is mainly
used in related measurement of the power industry to stably trigger the waveform
output from the transformer of a transformer substation.
