Oscilloscope Functions

In the Normal mode, the displayed waveform will be updated in the case of

triggering and not updated in the case of no triggering.

 Trigger source

The trigger source is used for generating trigger conditions. The user can

select the trigger source in the input signal of the input unit.

 Trigger slope

The slope refers to the change of the signal from low level to high level

(rising edge) or from high level to low level (falling edge). The slope used

as a trigger condition is referred to as the trigger slope.

 Trigger level

The trigger level refers to the level which the trigger slope passes through.

If the signal of the trigger source passes through the set trigger level

according to the specified trigger slope, triggering occurs. When the soft

key [Function] is pressed and “

Trig-Level” is selected, you can rotate the

knob to adjust the trigger level. In this case, the trigger level can be

changed by rotating the knob and you can observe trigger level changes on

the screen.
