Trigger sensitivity
Click [Mode&Sensitivity] menu key in the Mode menu, and then rotate the Multipurpose b to adjust the trigger
sensitivity. The trigger sensitivity range is 0.1
8 divisions, with a step of 0.1 divisions. The continuous
adjustment of trigger sensitivity can ensure HF Reject and LF Reject more flexibly and can accurately display and
analyze the measurement signal.
The trigger sensitivity is related to the trigger hysteresis of the digital comparator. If the signal is pure, the trigger
sensitivity can be set to 0.5 divisions or smaller, so as to ensure that small signal can be stably triggered. If the
signal contains noise, the trigger sensitivity can be set to 2 divisions or larger to ensure that the signal with large
noise can be stably triggered.
The trigger sensitivity is adjusted by the trigger
hysteresis of the digital comparator
