This repository contains an example Python module for PicoScope oscilloscopes.

• A PicoScope oscilloscope using one of the following PicoScope drivers:
  • ps2000
  • ps2000a
  • ps3000
  • ps3000a
  • ps4000
  • ps4000a
  • ps5000a
  • ps6000
• Python 2.7

• For best experience on Microsoft Windows Python(x,y) suite is recommended. Note that this will require the 32-bit PicoSDK to be installed (see Installing drivers)

• For Streaming mode data collection, the pytables module is required.
• The block_capture and streaming_capture examples require matplotlib and signal.
• PicoPyScope example has been written for use with PyQtGraph.

Notes: The code is not much different from Python3 and can be easily converted with the 2to3 utility. The module has been tested and proved working on Linux (including ARM derivatives), Microsoft Windows and Mac OS X.

Drivers are available for the following platforms. Refer to the subsections below for further information.

• Download the PicoSDK (32-bit or 64-bit) driver package installer from our Downloads page.

• Follow the instructions from our Linux Software & Drivers for Oscilloscopes and Data Loggers page to install the required driver packages for your product.

• Visit our Downloads page and download the PicoScope Beta for Mac OS X application.

A distutils installer is provided. After you have installed the PicoSDK driver package (see above), the Python installer can be used as follows:

python setup.py install

On macOS and Linux you will either need to use sudo with this command, to install into the system folders, or to install for the current user only you can use:

python setup.py install --user

Within python, the library for import is called picosdk.

• block_capture.py - comprehensive suite for testing block collection (-h to see all options)
• stream_capture.py - streaming testing utility, including some performance tests (-h to see all options)
• picopyscope.py - simple PC oscilloscope UI

Note: A basic script requires just a few lines as below. Most functions have been decorated with docstrings.

from picosdk import ps2000

if __name__ == "__main__":
    ps = ps2000.Device()
    status = ps.open_unit()
    if status == ps.m.pico_num("PICO_OK"):
        s, state = ps.get_channel_state(channel=ps.m.Channels.A)
        state.enabled = True
        state.range = ps.m.Ranges.r5v
        status = ps.set_channel(channel=ps.m.Channels.A, state=state)
        if status == ps.m.pico_num("PICO_OK"):
            s, index = ps.locate_buffer(channel=ps.m.Channels.A,
                                        samples=1000,
                                        segment=0,
                                        mode=ps.m.RatioModes.raw,
                                        downsample=0)
            status = ps.collect_segment(segment=0, interval=1000)
            if status == ps.m.pico_num("PICO_OK"):
                status, data = ps.get_buffer_volts(index=index)
                print data
                exit(0)
    print ps.m.pico_tag(status)
