Information about trigger channel

1. Information about trigger channel
Shows information about the selected trigger channel.
2

Option digital trigger

2. Option digital trigger
As trigger source a digital trigger or a threshold can be set.
3

Trigger polarity

3. Trigger polarity
The polarity of the trigger source can be changed. It can be chosen between npn and pnp.
4

Threshold

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.
