v3.0.0 | October 2019 | Andreas Svela

keyoscacquire is a Python package for acquiring traces from Keysight oscilloscopes through a VISA interface.

Based on PyVISA, keyoscacquire provides programmes for acquiring and exporting traces to your choice of ASCII format files (default csv) or numpy npy, and a png of the trace plot. The package provides a class Oscilloscope and data processing functions that can be used in other scripts. For example, to capture the active channels on an oscilloscope connected with VISA address USB0::1234::1234::MY1234567::INSTR:

>>> import keyoscacquire.oscacq as koa
>>> osc = koa.Oscilloscope(address='USB0::1234::1234::MY1234567::INSTR')
>>> time, y, channel_numbers = osc.set_options_get_trace()

where time is a vertical numpy vector of time values and y is a numpy array which columns contain the data from the active channels listed in channel_numbers.

If you need to find the VISA address of your oscilloscope, use the command line programme list_visa_devices provided by this package.

The code has been tested on Windows 7 and 10 with a Keysight DSO2024A model using a USB connection.

Note

In order to connect to a VISA instrument, NI MAX or similar might need to be running on the computer.
