While operating the oscilloscope, you may often use three features: Autoset, saving a setup and
recalling a setup. Hereinafter they are introduced one by one.

Autoset: This function can be used to adjust the horizontal and vertical scales of the oscilloscope
automatically and set the trigger coupling, type, position, slope, level and mode, etc., to acquire a
stable waveform display.

Trigger
The trigger determines when the oscilloscope begins to acquire data and display a waveform.
Once a trigger is properly set up, the oscilloscope can convert unstable displays or blank screens
to meaningful waveforms. Here introduce some basic concepts about trigger.

Source: The trigger can be generated with multiple sources. The most common one is the
input channel (alternative between CH1 and CH2). Whether the input signal is displayed or not, it
can trigger normal operation s . Also the trigger source can be any signal connected to an external
trigger channel or the AC power line (only for Edge triggers). Th e source with the AC power line
