Information about trigger channel

1. Information about trigger channel
Shows information about the selected trigger channel.

Option digital trigger

2. Option digital trigger
As trigger source a digital trigger or a threshold can be set.

Trigger polarity

3. Trigger polarity
The polarity of the trigger source can be changed. It can be chosen between npn and pnp.


4. Threshold
If Set threshold is activated, a threshold can be adjusted here, from which the signal is classified as high. A range of 0 to 11V is available. In order to compensate short level variations, a hysteresis can be defined additionally.
E.g. if a threshold of 8V and a hysteresis of 2 V is defined, signals higher than 8V are classified as high and signals lower than 6V are classified as low.
