Edge Trigger configuration menu
Use the Edge Trigger menu to trigger the oscilloscope when a signal rises and/or falls through a specified level.
To open the Edge trigger menu:
1. Double-tap the Trigger badge on the Settings bar.
2. Set the Trigger Type to Edge.
Settings panel (Edge Trigger configuration menu) fields and controls.
Field or control Description
Trigger Type Set to Edge.
Source Lists the source channel or waveform to use to trigger or search. Types that require multiple
inputs will replace this control with a different source definition control.
The MSO58LP also has an AUX edge trigger source, which sets the instrument to use a trigger
signal connected to the AUX front-panel connector.
Coupling Set the conditioning to apply to the source signal trigger circuit from the source signal.
DC coupling passes all input signals directly to the trigger circuitry.
HF Reject coupling attenuates signals above 50 kHz before passing the signal to the trigger
circuitry.
LF Reject coupling attenuates signals below 50 kHz before passing the signal to the trigger
circuitry.
Noise Reject coupling provides stable triggering by increasing the trigger hysteresis. Increased
hysteresis reduces the trigger sensitivity to noise so may require greater signal amplitude.
Level Sets the amplitude level that the signal must pass through to be considered a valid transition.
Set to 50% Sets the threshold at 50% of the measured signal transition range. 50% is calculated as (Top +
Bottom)/2.
Slope Sets the signal transition direction to detect. (rising, falling, or either direction).
