I'm seeing some odd behaviour with my new 3404A related to pulse width triggering. I'm hoping its not a fault but I dont see what else it can be unless there is a bizarre bug in the picoscope software.
All channels are functional and simple edge triggering works ok on all channels, but pulse width triggering only works as expected on channels A and B.
I am using a sequence of pulses of width 0.75ms, 1.5ms and 2.2ms and triggering from A or B I can selectively trigger on any of these widths.
Triggering from the same signal applied to C, D or Ext gets the result that width conditions 'less than' or 'outside range' trigger on any pulse, and conditions 'greater than' and 'inside range' never trigger.
Any suggestions ?
