Re: Trigger in Streaming Example

Hi When running streaming with the SDK it will start collecting data immediately with the trigger not being used to start the capture. In streaming the trigger is used to give the sample count at which the trigger condition is met for the first time. If you are wanting to use the trigger to start th...

Re: Acoustic Emission Measurement (Picoscope 3405D + python)

Hi The PicoPyscope is not something that we developed so can't give support on it, instead we have the picosdk-python-wrappers repository which contains python wrappers for the API functions for the scope series and examples on how to use these functions. This can be found here https://github.com/pi...

Re: Low-pass Filter on Matlab

Hi

There is the ps5000aSetBandwidthFilter function which allows for effectively putting a 20 MHz low pass filter on the input. Any other filtering in PicoScope 6 is a software feature and not available from the API functions in the PicoSDK.

Re: Resolving cause of Error 7

Hi

Are you able to give a overview of the GUI flow to the scope control from starting up till the error occurs?
This will help me understand how the functions sit in your GUI code.

Re: Bandwidth within the Picoscope software on Matlab

Hi To set the bandwidth limiter in MATLAB you need to call the ps5000aSetBandwidthFilter for each channel you wish to set the filter to 20 MHZ from the full range or to do the reverse. The details of the function can be found in the programmer's guide https://www.picotech.com/download/manuals/picosc...

Re: Wireless

Hi

The 4444 needs the USB connection to the PC for power as well as data transfer so there isn't a way to connect it wirelessly to the PC.
What exactly are you trying to do?

HI Pierre

You can input and output from the DrDaq at the same time from a single device.

Re: Pico SDK for MATLAB

Hi

The PicoSDK no longer contains the example scripts, these can now be found either through the MATLAB addon manager or from our Github page www.github.com/picotech

For a 5000A/B/D scope you will need the ps5000a MATLAB instrument driver addon and the picoscope support toolbox addon.

Re: How to use Ratio_Mode_Average

Hi The RATIO_MODE_AVERAGE downsampling work on the data in a buffer to average a number of samples equal to the downsampling ratio to create a single sample. There is not a way to average multiple buffers together on the scope, that would need to be done after the buffers are retrieved from the scop...

Re: High Sampling Rates using Python

Hi

It might be worth deliberately turning off the unused channels just to make sure that they are actually disabled.

Re: 8 bit resolution vs. values range

Hi Si

The 256 raw data levels of 8 bit resolution are scaled to 65536 data levels to be returned as a 16 bit number from the scope to the PC. This scaling is all done on the scope.

Re: picoscope peak to peak measurement

Hi Hans

A psdata file is a file type that the data can be saved as in PicoScope 6 that would allow me to see your signal and your set up.
