TriggerPoint of PCSU1000

Hello,

is the triggerpoint of the x-position a fix position? If yes, what time is it exactly if i use a sampling rate of 25MHz (Time/Div = 5 µs)?
Background: if i read the channel back with my programm i have to know exactly what dot od the 5000 was the trigger-point.

Yes, the trigger point is at fixed position. In theory it is at sample number 1024. Due to some hardware delay it varies a little. At 5us/div range the triggering occurs at sample number 1026.
You can check this by a square wave input. Set triggering on and read the data samples from 1020 to 1030 and look when the big change occurs in the data.
