Re: 11801 triggering

I think you gave the answer yourself: the rising edges of the waveforms are very close, so there is not enough time between trigger event and start of Cal output rising edge.
In my CSA803A I can view the rising edge of the FP clock output on a SD-26 when I set the CSA for internal triggering. And that is the rising edge starting at about 30 ns, so not the next one after 10 us. The (in my case slow) Cal output starts at about the same time position.
I tried the same as what you did when I was interested in trigger jitter of the external trigger input. IIRC Autoset even refused to obey.
As a nice exercise have a look at that next rising edge of the FP clock output (after 10 us). Jitter is about 200 ps rms.
