Trigger uses the analog or digital test circuits for triggering. It happens when the
input trigger source crosses a specified level in a specified direction.

Trigger
Trigger
Trigger , as a feature of analog oscilloscopes, gives stable displays of signals at
two different frequencies. Mainly it uses a specific frequency to switch between two
analog channels CH1 and CH2 so that the channels will generate swap trigger signals
through the trigger circuit ry .

to 80ms/div or slower. Normal

Mode updates the displayed waveforms only when the
oscilloscope detects a valid trigger condition. B efore this update, the oscilloscope still displays the
old waveforms. This mode shall be used when you want to only view the effectively triggered
waveforms. In this mode, the oscilloscope displays waveforms only after the first trigger.

Coupling: Trigger Coupling determine s which part of the signal will be delivered to the
trigger circuit. This can help to obtain a stable display of the waveform.
To
use trigger coupling,
push the TRIG MENU button, select an Edge or Pulse trigger, and then select a Coupling option.

: The Slope and Level controls help to define the trigger. The Slope option
determines whether the trigger point is on the rising or falling edge of a signal.
To
perform the
trigger slope control, press the TRIG MENU button , select an Edge trigger, and use the Slope
button to select rising or falling. The TRIGGER LEVEL knob controls the trigger point is on which
position o f the edge.
