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.
