Hi you first need to enable Auto, Repeat or Single Shot triggering at the bottom of the left hand side of the screen. You will then change the Source from being A to Ext.

Ah yes, this was posted on the "Writing Your Own Software" section didn't see that!

To answer your question:

short ps3000_set_trigger (
short handle,
short source,
short threshold,
short direction,
short delay,
short auto_trigger_ms )

the source which is a short with enumerated types so :

PS3000_CHANNEL_A (0), PS3000_CHANNEL_B (1),
PS3000_CHANNEL_C (2), PS3000_CHANNEL_D (3),
PS3000_EXTERNAL(4) or PS3000_NONE(5)

So external would be a value of 4 if you wanted to manually type it in.

Hope this helps.

Hi what signal are you feeding in (e.g. shape and speed)? Also how have you got it connected?
