Submitted by Oleksiy: Dear Alex, I had similar problem and contacted support. I think the solution using mex file will be more difficult as it need deeper knowledge on linking in Matlab. Perhaps if you ask Matlab support they will help you. It have something to do with dynamic and static linking. I ...

Submitted by Oleksiy: I have added library and header file from ps4000sdk to the previous set, thus it is functioning set now. Just to summarize: there is set of files to run three units Picoscope 4424 in Matlab environment. It is functioning, however troubles with memory management lead to occasion...

Hi Marco This version should work for you. I have tested it in LabVIEW 2010 and saved it for version 9. The problem was that the memory addresses of the arrays returned by PicoScope4000StartStreaming.vi changed when the VI returned. This didn't happen in version 8. Moving the terminals outside of th...

The conversion time is 2 seconds plus 1 second per active channel:

However, you can request values from the driver as frequently as you like. If a new value is not available, the old one will be repeated.

The dll should be in the SDK. It will also be in your PicoLog folder (C:\program files\pico technology\pico full)

I've posted it here too.

Hi I opened it and re-saved it in version 8.2. You should be able to open it now. I noticed that you changed your previous post. Regarding the library, make sure that the dll is in the same folder as the llb file. If it still can't find it, double click on the call library function node and select t...

Hi

All our software can be downloaded from www.picotech.com/software.html

Drivers/examples are included in the siftware development kits (SDKs)

Hi

I'm not sure I understand the question. If you are trying to get the time of (or between) triggers in rapid block mode, unfortunately this is not possible.

We have added new LabVIEW drivers and examples to the SDKs for the 4000, 5000 and 6000 series oscilloscopes. These should make development of LabVIEW applications using these products significantly easier. There is now a library of VIs that wrap the driver API functions. The below image shows how si...

Hi

All scopes use oversample * 'store length' of memory.

However, our 4000, 5000 and 6000 series scopes have significantly more memory (up to 1 GS).

Hi You can't have multiple programs accessing the TC-08 at the same time. Also, remember that the conversion time for the TC-08 is 100 ms plus 100 ms for each enabled channel. So if you have all 8 channels enabled, it will take 900 ms. The C example uses usb_tc08_get_single. For faster sampling, you...

ps4000con.c does use all channels in both block and streaming modes. See SetDefaults()

Hi I have just tried changing the #define BUFFER_SIZE up to 8000 (the 2204 has 8 kS of memory) and it appeared to be working correctly. As the line "timebase: 10 oversample:8" is not being printed, it sounds like ps2000_get_timebase is always returning zero (not that the driver is hanging), indicati...

Hi

We believe we have found and fixed the problem.

I have attached an updated driver. Please let me know how you get on with this.

Hi

Sorry, I should have read your post properly!

It does look like there is a bug somewhere causing the device to not auto-trigger. I found that the unit would trigger if I applied a signal. Is this the case for you?
