I'm one of those who prefers to hide in the background, and have been doing so for ages!

I am quite happy with the merge function but would like to get further functionality from it.  My scenario is this:

If I have two files of say secondary ignition with 2 or 3 events per wave form, and want to compare the 2nd event on one waveform with the first event on the other waveform,  once the files are merged, I would like to time shift one waveform relative to the other.

Is this possible within the software?

Thanks

Andy

Composite funcitons are somewhat dependant on what scope you have the newer usb currently need to be connected to do composite views.

There are several composite view options if you zoom and use the original view you can move the waveforms around and it will display them moved on the composite view.  This is with the 212 series but I suspect similar can be done with the usb scopes

Many thanks for the help :)

I hadn't worked out that the composite view was 'live' and that changing the original views could change the composite.  

I have a scope in the 212 range, so it works just as you described. ;D

Your comments raise a further question.  I am about to purchase a further scope, which of course will be of the Pico variety.  If I get a usb unit, which makes sense in most respects, would I be able to do the same (i.e. create a composite of 2 saved waveforms) so long as I have the scope connected?

Hi Andy,

Yes, you can merge and composite the same as the 212.  The current 5.13.07 will merge and composite 3000 series files without the hardware attached.

We have a four channel upgrade option, when you are ready to upgrade.  This option includes the Autonerdz support system which would be $350 per year, if purchased separately.

Jarvissamuel,  thanks for the info, I'm well on the way to getting what I want.  I seem to be only able to scroll any particular waveform by an integral number of screen divisions.  Is this a software limitation or is it possible to scroll the X-axis by fractions of a division?

Tom, Thanks for the info on the usb scope.  I'm looking forwards to getting a new scope ;D

I am not sure I understand exactly what you are asking but  there is only ten divisions on the horizontal axis.  It is possible to have more than one screen saved but it requires a save on trigger session

I would love explain things clearly like many of you lot do ;) I'll try again:

I have created a composite of two zoomed waveforms, and wish to align one event on the first waveform with another event at a later time on the second waveform.  This requires scrolling the x-axis (time) on window two to align the events.  

The problem I have is with this scrolling, in that I am only able to scroll the time by one time division, whatever that might be, which is dependent on the zoom factor.  If this is correct, I cannot exactly align the start of the event on both waveforms as they will never be fortunate enough to be at an integral number of time divisions apart.

OK still not exactly sure but is the zoom you are using on the top of the screen after the composite is created are you using the use original view feature and zooming on each individual file?

The zoom on the top of the screen is usually displayed as soon as a composite is created it will usually automaticly display the waveforms usually in an overlay view

If you minimize each screen on a 2 file merge view there should be 3 screens the 2 files and the composite view.  When the use original view is used any changes made in the original files will be displayed in the composite view.

composite views can also be saved so if were still not on the right track maybe we could look at the psd or you could do a screen shot and upload it.

Just an announcement on this subject:  

Enough of the composite view display issues were resolved to enable me to make that long awaited tutorial movie on Composite Viewing.

It is now available, to group members, in the Tutorial Library section of the PicoScope Users Area.
