The Matplotlib is a library for creating 2D plots of arrays in Python. The purpose of this blog entry is to depict a general approach to enable continuous updating of figure data during the Python script execution. The figure update functionality is useful for plotting measurement data that is recorded with the Zurich Instruments HF2LI Lock-in amplifier.

Controlling the HF2LI Lock-in with Python

on 04.05.2011 at 16:45 by Lara Juricic
This blog entry contains a basic example how to communicate with HF2LI Lock-in using the Python programming language. This is achieved with an interface library of Zurich Instruments that transforms the ziAPI into a native Python interface.

Controlling the HF2LI Lock-in with Matlab

Controlling the Zurich Instruments device directly with Matlab is extremely powerful for repetitive measurements and scripting. This blog entry explains a method to communicate with the ziServer directly from Matlab. This interface is very fast and thus well suited to record large data sets at high-speed.

R recorded with Zurich Instruments HF2
The combination of Zurich Instruments devices and Matlab is a powerful tool set to get your application measured. In a first step I show a method to load the demodulator data of the Zurich Instruments HF2LI lock-in amplifier into the Matlab workspace. This approach uses the graphical user interface of the HF2LI to save the data in binary format. In a later blog entry a will show another method which allows for direct control of the HF2LI from Matlab. This enables scripting and recording of large measurement data sets.

Pixelgraphics of the SVG Plot.
The following example of a histogram plot uses filter to fill figure elements with pixel images. The histogram bars will drop a shadow. The axis labels will be rotated by 90 degree to improve readability. All these additional effects are […]
