Slider for setting of trigger level

The button "Trigger mode" is used to activate the input functions for setting the trigger signal.

The trigger level can be changed by moving the slider. Shift upwards to select positive voltage values, and downwards to select negative values.

The signal connection (e. g. DSO 1, DSO 2, pick- up, kV) for the trigger signal can be selected by pressing the button "Channel".

When pressing the button "Coupling", a selec- tion menu appears depending on the selection of channel A or B. High-frequency or low-frequency filtering of the trigger signal can be carried out in this menu.

The buttons "Coupling" and "Edge" are omitted if the signal connection "Pick-up" is selected.

The button "Edge" opens a further menu with the possible selections "neg." or "pos.". The falling edge of the trigger signal or input sig- nal is used when selecting "neg.", the rising edge when selecting "pos.".

When connecting the measuring leads of the DSO, check that the polarity and the respective connection points are correct. The signal shape is largely determined by the connection points. Both signal cables should preferably be connected to the sensor or actuator.
