TRIGGER
Use this function to configure settings for the trigger and trigger type.
Set Trigger and Trigger type. For Trigger function, press key a short second.
For level change, press key longer than 2 seconds to enter the level mode of
Edge Trigger and change level by Encoder Switch.
Edge
Use to acquire the waveform from the rising and falling edge of the signal for
the trigger level. Setting value of Trigger source and Trigger slope is displayed
on screen.

Coupling
(DC/AC/HF Rej./LF Rej./Noise Rej.)
As this sets the trigger source coupling, it must be selected to match the
situation to observe.
- DC Coupling
The selected trigger source is applied to the trigger input unchanged. This is
identical to using the actual displayed waveform as the trigger source.
- AC Coupling
Passes the selected trigger source through the capacitor and a signal without
the AC component applied to the trigger input.
- High Frequency Rejection
A signal with the high frequency component removed from the selected
trigger source is applied to the trigger input. This is used to observe low
frequency signals with a high amount of high frequency noise.
- Low Frequency Rejection
A signal with the low frequency component rejected/removed from the
selected trigger source is applied to the trigger input.
- Noise Rejection
A signal with noise removed from the selected trigger source is applied to
the trigger input.
When comparing the trigger source and level, this adds hysteresis and
disregards the noise within the source near the trigger level, and recognizes
the overall slope as the trigger point. When the noise is excessive and when
simultaneously observing the Rising/Falling edge while acquiring the
waveform, set the noise reject coupling to acquire the waveform only on the
desired slope.
