LabOne Highlights

What's New?

With every new release of LabOne, a range of additional functionality expands your Instrument's capabilities even further while maintaining the highest quality standards you have come to associate with Zurich Instruments. This page summarizes some of the most recent highlights.

Waterfall display and triggered spectrum analysis

The LabOne Spectrum Analyzer is a powerful tool to analyze measurement signals in the frequency domain, helping in the measurement of sidebands, in quantifying multiple signal components, or in characterizing various noise sources. You can zoom into sub-Hertz features even on signals in the hundreds of MHz.

With LabOne release 17.12, this widely applicable tool got a lot more graphical and powerful: It now features a waterfall display or spectrogram, facilitating the analysis of spectra that evolve over time. In addition, we added the triggered acquisition of multiple spectra with precise timing and display the result in a 2-dimensional color plot. The triggered data acquisition is now provided by the new LabOne Data Acquisition tool, which is an entire rework of the previous module called Software Trigger.

With these additions, measurements of transient phenomena such as free induction decay (FID) in NMR spectroscopy are greatly improved: measurements can be done right away in the graphical user interface saving the time and back-and-forth of data post-processing. Triggered acquisition is particularly useful on the UHFLI instrument with UHF-AWG Arbitrary Waveform Generator option. Such a system combines pulse generation, synchronized acquisition, and powerful software for time and frequency domain analysis, making it the perfect tool for pulsed measurements.

Q-factor extraction from Sweeper data

In a variety of applications such as MEMS, AFM, gyro, sensors, etc. the Q-factor of resonators is required to establish a closed-loop control system like a PLL following the resonance track of a tuning fork. Moreover, Q-factor determines the damping characteristics of oscillators such as lasers and clock generators. Hence, it is essential to extract the resonator Q-factor rapidly and accurately from its measured frequency response. With the 17.12 LabOne release we added a mathematical tool to the Sweeper module capable of Q-factor extraction. By measuring the frequency response of a resonator, one can set the cursors around the peak and add the Resonance parameters in the Math tab. As depicted in the following figure, the tool fits the measured curve (solid line) to a Lorentzian model (dashed line) and extracts the resonator parameters including the quality factor, resonance frequency, 3-dB or FWHM bandwidth for both amplitude and phase independently.

Improved Impedance User Interface and Functionality

The latest release of LabOne brings a new, much improved Impedance Analyzer Tab to both the MFIA and the MFLI with MF-IA option. The new tab gives fast access to all key set-up parameters and keeps the other parameters neatly stored away, ready for use whenever needed. The new layout consists of three sections allowing the measurement to be quickly and clearly defined and always visible while using the sweeper or plotter.

Measurement Control

Easy access to the test signal, test frequency, and range control (auto or manual). The new application menu allows simple selection of typical measurement frameworks, which can then be tweaked using the advanced mode. The “precision” menu allows you to choose the balance between acquisition speed and precision.

Equivalent Circuit

Select the mode of measurement with the help of the graphical representation of the measurement circuit. The two-component equivalent circuit can easily be selected from the drop-down menu.

Measurement Results

This new section displays real-time values of the key parameters, without having to switch to the numeric tab.

Parametric Sweeper

In addition to the improved impedance analyzer tab, the sweeper has been improved and now includes the ability to run Nyquist-plots (see screenshot). The plot can be freely configured, and the axis scales can be locked using the new “Track” feature, which allows the Nyquist-plot to be displayed in a true 1:1 ratio.

Multi-device Synchronization (MDS)

Do you have an application that requires the use of multiple synchronized signal input and signal output channels? Then you are probably well aware that just stacking a few instruments is often not sufficient.

Full synchronization includes stable and well-defined phase relationships between the various reference clocks, the ability to synchronize the signal outputs at defined times and the alignment of time stamps and sampling rates for the recorded signals. Ideally, you have to use only a single user interface or API to orchestrate the entire instrument assembly.

Zurich Instruments is committed to providing customers a comprehensive approach and offer the best-in-class scalability of their instruments. Starting with LabOne 17.06, users that operate several Zurich Instruments devices simultaneously will now be able to synchronize their instruments and use them through a single instance of Labone.

  • Clock synchronization: locks all internal instrument clocks to one master clock
  • Time stamp synchronization: aligns measurement sampling rates and time stamps taken by different instruments for convenient further processing
  • UHFAWG output edge synchronization: aligns the signal generation engines at any point of the sequence to produce edges with a defined maximum skew
  • UHFAWG sequencer synchronization: control the output of several AWG instruments from one single sequencer program with distributed execution

Multi-Device Synchronization also includes the LabOne toolset on the user interface and through the APIs. The following data acquisition and data analysis tools are MDS ready:

  • Sweeper: sweep a parameter on one instrument and acquire data from multiple instruments in a single user interface or API
  • Plotter: analyze the measurements performed on multiple instruments in a single Plotter window
  • Software Trigger: trigger on any signal and acquire shots of aligned data from multiple instruments into a single Software Trigger window
  • Continuous aligned data recording: record fully synchronized Lock-in, Boxcar, PID, Arithmetic Unit (AU) and Scope data via the user interface and API from multiple synchronized instruments

Imaging with the Data Acquisition Module

Imaging is one of the most important applications for our customers doing Scanning Probe Microscopy (SPM) and non-linear imaging, with CARS, SRS and THz spectroscopy, being the most prominent examples.

The imaging mode converts any of the measurement signals into images and provides

  • A clear definition of a "line", based on a starting event detected by the line trigger and a user-defined duration.
  • The resampling of the recorded data samples to the required number of pixels with a suitable interpolation and/or averaging.
  • To store the matrix-like data in a grid data structure, based on the number of lines defined.

All this is now implemented in the LabOne Data Acquisition module and available in the user interface as well as on the programming interfaces (API). With the power to stream up to a sustainable 800 kSa/s over multiple channels in a triggered fashion (depending on product category), the LabOne server architecture is strong in data acquisition capability, even video rate (512*512 pixel/s) would still be well below the transfer rate limit.

Graphical Lock-in Tab - Functional Block Diagram

By adding a functional block diagram for every demodulator to the LabOne user interface the user can now intuitively understand the signal processing pathways. Signal Input and demodulator settings, as well as the various output channels - Signal Outputs, Auxiliary Outputs and the data transfer to the PC - are all covered.

File Manager

The File Manager was introduced as a new tab with the latest release. For UHFLI users this brings the advantage of a quick and easy access to measurement files, settings files and log files on the local PC. Moreover, MFLI users can manage files on the instrument flash drive as well as on storage devices attached to one of the two USB connectors.

Presets

The UHFLI and the MFLI can now be programmed to start up in a user defined state of operation. This is particularly interesting for applications where the same instrument configuration is always needed and results are mainly taken out from the auxiliary outputs. Typical examples are imaging applications with analog interfacing to the main controller.
