External trigger

Products & Technology DSO Quad
#1

I have looked through the seeed manual, other manuals and the WIKIS but cannot find details of external or “other channel” triggers.
Is there a separate external trigger connection.
Which, if any, channels can be used together as trace and trigger.
If so, can dissimilar voltages be used simultaneously for trace and trigger.
Thanks

There is no specific external trigger circuit on the Quad. The device has 5 external connectors; 2 analogue, 2 digital inputs and 1 waveform out. You can use any of the 4 inputs as a trigger source and they can also be displayed at the same time. A digital input could provide a trigger for viewing dependent analogue signals or vice versa.
