Re: Problem for icdevice

After you set the peaktopeakVoltage property do you call the function to run the signal generator again?

Re: Picolog 6 - multiple instances

PicoLog 6 can only have a single instance open at any one time but this instance can control multiple devices.

Re: Data Collection issue in / PicoScope 6403A / Python 2.7 / Windows 10

I've tried to reproduce what you've been seeing and have been unable to do so.

Are there any other applications running when you're doing this?
Are any other devices using the USB bus while this is running?
What are you doing with the graph each time its plotted?

Re: Can't use any python librairy

Hi Are you able to post the full code that you're using from the python-wrappers including the settings you're using for the scope? Have you checked in the programmer's guide that you're passing values that are correct for the 6407? https://www.picotech.com/download/manuals/picoscope-6000-series-pro...

Re: Data Collection issue in / PicoScope 6403A / Python 2.7 / Windows 10

What is producing the signal that you're trying to collect?
Are you able to get the capture to work in PicoScope 6 using the same settings as you're using in python?

Also what happens if you move this line
ready = ctypes.c_int16(0)
before calling runBlock?

Where exactly in the script does it fail? Do you get any error codes?

Re: Data Collection issue in / PicoScope 6403A / Python 2.7 / Windows 10

Hi We don't support that wrapper as it wasn't created by us. Have you tried using our wrapper for controlling the scope, if you're using this wrapper then we can assist you. https://github.com/picotech/picosdk-python-wrappers If you're wanting to continue using the wrapper by Colin O'Flynn and Mark ...

Re: Data Collection issue in / PicoScope 6403A / Python 2.7 / Windows 10

Hi

I'm currently looking through your code and need some more information to understand it.
Where does your picoscope import come from?
Also you seem to be using functions on your picoscope object that don't exist within the picosdk-python-wrappers repository, where are these defined?

Re: Problem for icdevice

Hi

In the examples part of the PicoScope 5000 A API MATLAB Generic Instrument Driver add on there is a signal generator example that shows how to program the signal generator with the API command.

Re: Problem for icdevice

Hi

Do you have the scope open in any other software such as PicoScope 6, while you are trying to use the scope within MATLAB?

Re: Problem for icdevice

Hi

What device are you using?
Have you got the PicoScope Support Toolbox downloaded and on the MATLAB path?

Re: Old aged MATLAB, R2009A can control PICOSCOPE 5000D?

Hi We don't test with versions earlier than 2015b, so have no information whether 2009a is able to support the running of one of our scopes It is possible to control the scope without the instrument control toolbox, if you want more information about this method please email into support@picotech.com

Re: How is Samples setting default derived?

Hi

The 2205A has an internal memory of 16k which is why that's the default when its connected in PicoScope 6

Re: Is there a way to trigger the scope via software?

Hi That is correct if you have no trigger set on calling runBlock it will immediately collect the full number of samples asked for i.e pre-trigger + post-trigger. There isn't a way to use a software trigger for collection, you would need to set up an appropriate trigger to collect pre-trigger sample...
