Hi Don,
?
QI. So we meet again in another place ;) Seems I 'triggered' you to update the firmware.
?
Erik, I commented on a video of Don with the following:
?
'As far as I understand setting trigger to 'auto' does not trigger at all, it is normal SA mode. So you are taking snapshots of the signal 16.7 ms apart, but not synchronised. Hence the moving spikes. To trigger the signal to be stable you should select 'normal' and delay just above 16.7, let's say 20 ms. Yes, it will skip one spike, but the next spike will trigger at the same place. '
?
We had a little discussion about this but since there is no clear explanation on this feature in the WiKi any help/clarification from you would be helpfull.
(As for me: some help on the extended trigger feature to trigger on a trace would also be nice.)?
?
One of the things I noticed is that the sweeptime on the ultra is not constant: e.g. if I set the sweeptime to 50 ms the actual sweeptime in zero-span differs with every sweep +/- some ms. That would also explain Don's problem with the interval not giving a steady picture: every sweep has a slightly different time.
?
Regards to both,
?
Henk
