Problem with setting trigger from VB in PiccoScope3204

Post by tobo » Thu Sep 29, 2005 3:13 pm

Dear Pico Users,

I have a problem for which I can not find a solution. Moreover the helpdesk of Pico is unable to help me either :(

I mean, I need to measure period between CHA & CHB of approx. 4ms.
There should be a trigger set on CHA and later when it is released, samples should be stored in the memory to fetch them later.

I need to configure the trigger as follows: CHA, rising, 900mV.

Then I wrote following command's order:

ps3000_handle = ps3000_open_unit()
i = ps3000_set_ets(ps3000_handle, 0, 0, 0)
Ret = ps3000_set_channel(ps3000_handle, 0, 1, 1, 8 )
Ret = ps3000_set_channel(ps3000_handle, 1, 1, 0, 3)
Ret = ps3000_set_trigger(ps3000_handle, 0, 115, 0, 0, 0)

All is fine but after using ps3000_set_trigger I received "0" so it means that some parameters are out of range. But why?
How can I set the trigger in VB then?

For the response I'd like to thank you in advance!

Best regards,
Tomasz Bobrowski.
