With every new release of LabOne®, a range of additional functionalities expands your instrument's capabilities while maintaining the highest quality standards associated with Zurich Instruments. This page summarizes some of the most recent features.
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 becomes 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 was entirely reworked from a previous module called Software Trigger.
These additions benefit greatly measurements of transient phenomena such as free induction decay (FID) in NMR spectroscopy. Triggered acquisition is particularly useful on the UHFLI with the UHF-AWG Arbitrary Waveform Generator option installed. 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 applications such as MEMS, AFM, gyroscopes, sensors, etc., the Q-factor of resonators is required to establish a closed-loop control system such as a PLL following the resonance track of a tuning fork. Moreover, the Q-factor determines the damping characteristics of oscillators such as lasers and clock generators. Therefore, 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 for Q-factor extraction to the Sweeper module. By measuring the frequency response of a resonator, it is possible to 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 much improved Impedance Analyzer tab to both the MFIA and the MFLI with the 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, which remain visible when using the Sweeper or Plotter tools, enabling quick and clearly defined measurements.
Obtain easy access to the test signal, test frequency, and range control (auto or manual). The new application menu enables a simple selection of typical measurement frameworks, which can be modified further in the advanced mode. Notably, the Precision drop-down menu allows you to choose the balance between acquisition speed and precision.
Select the mode of measurement with the help of the graphical representation of the measurement circuit. The two-component equivalent circuit can be easily selected from the corresponding drop-down menu.
This new section displays the real-time values of key parameters without having to switch to the Numeric tab.
In addition to the improved Impedance Analyzer tab, the Sweeper tool now includes the ability to run Nyquist-plots (see figure). The plot can be configured freely, and the axis scales can be locked with the new “track” feature, which allows the Nyquist-plot to be displayed in a true 1:1 ratio.
Multi-Device Synchronization (MDS)
Starting with LabOne release 17.06, users operating several Zurich Instruments products simultaneously can synchronize their instruments and use them through a single instance of LabOne.
Applications requiring multiple synchronized signal input and signal output channels benefit from multi-device synchronization (MDS), which provides clock synchronization and time-stamp alignment. MDS also enables you to orchestrate the entire instrument assembly through a single user interface or API session. The following signal generation and data acquisition tools are MDS-ready:
- AWG: control the output channels of several AWG devices from a single sequencer along with sample-wise synchronization of all output waveforms.
- Sweeper: sweep a parameter on one instrument, and acquire and plot data from multiple instruments in a single figure simultaneously.
- Plotter: align and analyze the measurements performed on multiple instruments in a single Plotter window.
- Data Acquisition: trigger on any signal and acquire shots of aligned data from multiple instruments into a single image construction window.
- Continuous recording of aligned data: acquire fully synchronized lock-in, boxcar, PID, Arithmetic Unit and Scope data from multiple instruments.
Imaging with the Data Acquisition Module
Imaging is one of the most important applications for our customers working in Scanning Probe Microscopy (SPM) and non-linear imaging (with CARS, SRS, and THz spectroscopy being 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 defined lines.
All this is now implemented in the LabOne Data Acquisition tool (DAQ), and is available in the user interface as well as on the APIs. 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 its data acquisition capability: even video rates (512*512 pixel/s) would be well below the transfer rate limit.
Graphical Lock-in Tab – Functional Block Diagram
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's flash drive as well as on storage devices attached to one of the two USB connectors.
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.
