When there is low frequency noise in the waveform, stable edge triggering can be obtained using LF rejection
coupling.
5)
NoiseRej. (Noise Rejection Coupling) - Noise rejection can add extra hysteresis to the trigger circuit. By
increasing the trigger hysteresis band, the possibility of noise triggering can be reduced. But it also reduces the
trigger sensitivity, so triggering the oscilloscope requires a slightly larger signal.
Note:
Trigger coupling is independent of channel coupling.
6.3 Pulse Width Trigger
The trigger happens when the trigger signal pulse width (8ns~10s, the trigger type indication icon at the top of the
screen is
) reaches the set condition and the signal voltage reaches the set trigger level. Pulse width trigger
menu is shown in the following table:
