Hi Cupidus83, The MATLAB Instrument Driver has now been updated to support changing the resolution of the PicoScope 4444 (release 1.12.2.2 beta or later). Please refer to the latest GitHub release for this Instrument Driv...

Hi cah00, Please try the following: * Set the numPreTriggerSamples property to 0 * Call the ps5000aGetTimebase2 function once (refer to PS5000A_ID_Block_Example.m script included as part of the package) to confirm that the sampling interval is as expected for the timebase selected * Set the autoTrig...

Hi SE21733, If you use the prototype and thunk libraries from our example on File Exchange then it removes the need to use Windows SDK 7.1 and run mex-setup on your PC. Please also refer to the example for how to load the library using the above files and note the change in the case name for the dll...

Hi ehliar,

This is a known issue if data collection is stopped without calling HRDLCloseUnit(). An issue has already been logged, and should be investigated in the future.

For the time being, please use the workaround that you have.

Hi ehliar,

This is an issue that we have been made aware of previously and has recently been fixed in the driver. I am unable to advise when the fix will be made available but do check for updates to the driver package in a few weeks.

Hi Mattia, Sorry for the delay in someone responding to you. The MATLAB Instrument Driver unfortunately does not report back the actual frequency being output (there isn't a function to do this in the shared library). However, it should be possible to calculate this using the formula in the delta ph...

Hi Eric,

An error code of 16 is USBTC08_ERROR_COMMUNICATION - the PC has lost communication with unit - this is in the USBTC08_ERROR set of enumerations in the usbtc08.h header file.

I will put in a request for the documentation to be updated.

Hi sejinoh72, There is an updated picotech_ps4000a_generic.mdd file (v1.2.15) available via File Exchange. Please update to this and let us know if it resolves the issue. It will display a warning if it detects the status code, but all you need to do is invoke the ps4000aSetChannel() function with t...

Hi Krzysztof,

Have you installed the PicoScope Support Toolbox?

If so, please e-mail support@picotech.com and a member of our Technical Support Team will provide you with an updated 64-bit PicoSDK installer which should be compatible with the PicoScope 5444D.

Hope this helps,

Hi mc1, You might be able to use the ps4000aGetValuesBulk() function in the Rapidblock group to retrieve a number of waveforms at once if you are using segmented memory. This will require you to setup your data buffers using the ps4000aSetDataBuffer() function and also convert the data from ADC coun...

Hi ebieirene,

If possible, please e-mail support@picotech.com including the psdata file corresponding to the data you are trying to export to .mat format and this will be investigated further.

Regards,

Hi Username2018,

We have received your e-mail support request and will respond via that.

If a new example is created, we will share it via our GitHub repository.

Hi Mat, Is there any non-zero code returned when calling ps5000aRunBlock()? It might be useful to post the code sequences here leading up to the retrieval of data if possible or send it to support@picotech.com The only thing that should happen when the device is connected on a USB 2.0 port is that t...

Hi gerardtouma, Would it be possible to post your code here or send it support@picotech.com so we can investigate further please? Do you see the same effect with the PicoScope 6 software at all? What is the source of the 120 MHz sine wave? Which version of the PicoSDK and MATLAB are you using? Regar...

Hi Chris, How have you defined the ps5000aDataReady() callback function? You could try setting the lpDataReady() parameter to None and poll ps5000aIsReady() until the driver indicates that data is available. Otherwise, there is the ps5000aGetValuesOverlapped() function which could be used. Regards,
