Control Your Measurements With QCoDeS and Labber

on 24.05.2020 at 19:08 by andrea on Blog of Andrea Corna
With this blog post, we introduce a new high-level Python programming interface for Zurich Instruments devices: the Zurich Instruments Toolkit. It is the basis of our new support for QCoDeS and Labber measurement frameworks. A modern experiment can nowadays be a […]

Zurich Instruments Users Meeting in Leiden, The Netherlands

on 17.06.2015 at 11:58 by Daniel on Blog of Daniel Wright
On June 3rd my colleague Romain Stomp and I welcomed Zurich Instruments users with a focus in Scanning Probe Microscopy (SPM) to visit us for the day at Leiden University in the Netherlands. In the morning, Romain shared his expertise with a presentation outlining […]

LabOne Programming Manual

on 30.06.2014 at 11:24 by Daniel on Blog of Daniel Wright
In addition to the LabOne User Interface Zurich Instruments lock-in amplifiers can be controlled simultaneously via any of the available LabOne APIs: LabVIEW, Matlab, Python or C. Zurich Instruments software release 14.02 includes the LabOne Programming Manual which guides users to an appropriate choice of API […]

Reduce Ground Disturbances when using HF2TA Transimpedance Amplifier in a Measurement Setup

on 26.02.2014 at 18:13 by James Wei on Blog of James Wei
Ground loops can potentially pose a serious problem in many measurement setups. Due to the multiple connections to and from the HF2TA current amplifier and other external components, several ground loop related issues can pop up in the signal being […]

Using HF2IS Impedance Spectroscope for FRA, 2-Terminal and 4-Terminal Measurements

on 19.09.2013 at 14:14 by James Wei on Blog of James Wei
Often there are questions from our HF2IS Impedance Spectroscope users on how to configure the HF2IS for frequency response analysis (FRA), 2-Terminal impedance measurement, or 4-Terminal impedance measurement. This short blog will clarify the proper physical connections as well as […]

Remote Access to HF2 Instruments on the LAN

on 07.06.2013 at 08:56 by James Wei on Blog of James Wei
As explained in the HF2 User Manual, users can configure in ziControl to connect to any ziServer host on the LAN i.e. remote client access to HF2 Instrument. This blog will sum up an easy two-steps procedure to do exactly […]

Optimize Your HF2TA Transimpedance Amplifier Settings

on 24.05.2013 at 11:43 by James Wei on Blog of James Wei
Users of the HF2TA transimpedance amplifier should always be aware of the trade-off between the transimpedance gain and the 3-dB roll-off bandwidth of the amplifier. (Hint: Since the HF2 software release 12.08, the bandwidth is also specified in the HF2TA […]

Optimize Your Frequency Sweep for Static Impedance Measurement

on 28.02.2013 at 08:20 by James Wei on Blog of James Wei
Very often people want to measure very large static impedance (e.g. small capacitance, large resistance) over a wide frequency range. In the very low frequency region, one may notice that measured curve is not smooth but rather “jiggly”, just like […]

Q-Control Example VI Tutorial

on 04.12.2012 at 19:45 by andreas on Blog of Andreas Senn
Using a Zurich Instruments lock-in amplifier, you are enabled to measure the quality factor of an arbitrary resonator – typically a resonant beam used in non-contact atomic force microscopy (NC-AFM) applications. This can be useful e.g. to increase phase sensitivity […]

Dynamic Plotting of HF2 Lock-in Data with Python

on 03.11.2011 at 18:06 by Lara Juricic on Blog of Jürg Schwizer
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 Zurich Instruments Devices with LabVIEW

on 06.09.2011 at 14:56 by Andrin on Blog of Andrin Doll
With Zurich Instruments LabVIEW driver, you can integrate your device into complex laboratory setups and create your own graphical interface for simplified experiment control.The driver provides access to all adjustable parameters and measurement readings of your Instrument.
In this post, I explain on the VIs included in our LabVIEW driver and on a simple example on parameter setup and data streaming. LabVIEW beginners find a link to our Getting Started for guaranteed programming success in LabVIEW.

Controlling the HF2LI Lock-in with Python

on 04.05.2011 at 16:45 by Lara Juricic on Blog of Jürg Schwizer
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

on 03.01.2011 at 10:33 by Jürg Schwizer on Blog of Jürg Schwizer
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.

Loading HF2LI Lock-in Measurements with Matlab

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.
