Hi Stefan,

I have two problems regarding using the drs_exam file with external trigger:

1- I connected a 200Khz signal with 20ns rising edge, 50 ohm load, and 27% duty cycle as an external trigger. The output of the drs_exam file starts from 0 to 200ns. Since I use an external trigger, I think it should be starting from 0 to 5ns and then again starting from 0. Could you please tell me where the problem is?

2- How is it possible to change from 1024 to 2048 bins in the drs_exam example?

You can find my code in the attachment.

Best regards,
Mehrpad
