Re: Externally triggered AWG burst (shots).

Oh that's a shame. Guess it doesn't matter that I forgot to attach my VI then!

Thanks,

Christian.

Re: Externally triggered AWG burst (shots).

Hi Hitesh, Thanks, I've tried what you suggested but it didn't majke a difference. In fact, I've realised that it's nothing to do with trying to use the scope and AWG simultaneously - it's just that I can't get triggered shots to work at all. I've attached a zip containing a VI called AWG_tester.vi ...

Externally triggered AWG burst (shots).

Hello, (PS4226, LabVIEW 2012) I'm making something that, on receipt of an external trigger signal into chB, will fire a burst of N cycles (shots) from the AWG and simultaneously acquire data from chA (at the moment I've just got the AWG output wired straight into chA). If I set the AWG trig type to ...

Re: Rapid Block Mode LabVIEW PS4224

Thanks that's cleared things up. I managed to get some numbers out of GetValuesTriggerTimeOffsetBulk64 using the new DLL, but I'm not sure how to use them. Some of them are negative and they seem to change randomly between timeUnits. I implemented it like this, can you see what's going wrong?: http:...

Re: Rapid Block Mode LabVIEW PS4224

Thanks alot. I'm having a few problems still though :arrow: Is the new ps4000.dll supposed to entirely replace the old ps4000.dll? If I only use the new ps4000.dll for GetValuesTriggerTimeOffsetBulk64, and keep the rest of the functions loading from the old ps4000.dll and ps4000wrap.dll (I had to re...

Re: connect 2 computer have Labview software on the network

I think this is what you need http://zone.ni.com/devzone/cda/tut/p/id/2710 but, as Robin said, you'll be much better off posting further queries about it in the national instruments labview forums here http://forums.ni.com/ni/board?board.id=170 since your problem really has nothing to do with your p...

Re: Rapid Block Mode LabVIEW PS4224

That works great, thanks very much. Why is it that you have executed getvaluesbulk one time for each waveform (in the for loop) and not just once so that it retrieves all the waveforms at once as suggested in the programmers guide, where it sets the from segment index and to segment index differentl...

Re: Rapid Block Mode LabVIEW PS4224

Thanks for your reply. As far as I can tell I'm doing everything it says in the Programmer's Guide, although my understanding of C is poor so I'm finding it difficult to implement the C examples provided in the document as LabVIEW code. One specific problem: the Programmer's Guide states to use ps40...

Re: use the picoscope 2104 to measure

Hi, You need to pass your aquired waveform through LabVIEW's 'Extract Single Tone Information' VI, which finds the frequency of the componant of your signal with the highest amplitude. It's in Signal Processing> Waveform Measurements Or, if your signal is more complex (it doens't look like it from y...

Rapid Block Mode LabVIEW PS4224

Hi, I'm having some trouble adapting the LabVIEW block mode example that comes with the 4224 so that it uses rapid block mode. I've been following the guide here http://www.picotech.com/document/pdf/ps4000pg.en-3.pdf (page 10) which includes C++(?) examples. Does anyone know of any LabVIEW examples ...
