The SDK document describes the 'delay' parameter thus :
delay, the delay, as a percentage of the requested number of
data points, between the trigger event and the start of the block. It should be in the range -100% to +100%. Thus, 0% means that the trigger event is at the first data value in the block, and -50% means that it is in the middle of the block. If you wish to specify the delay as a floating-point value, use ps2000_set_trigger2()
This does not make sense! If the range is -100 to +100, then -50 would be one-quarter of the way into the block, not half way, and 0% would be the middle not the start!
Can we have some calrification on the actual value to be entered here please!
For reference I looked at what PicoScope 6 does - and the range it lets you specify is 0% to +100%.[/b][/quote]
