Teledyne LeCroy has unveiled the VectorLinQ vector signal analysis software option in order to expand the capabilities of its oscilloscopes. According to the company, VectorLinQ enables sophisticated visualisation and analysis of standard modulation schemes including n-PSK, n-QAM, circular QAM, ASK and FSK, as well as custom signal types and symbol positions.

The VectorLinQ software includes functionality to either demodulate RF signals for analysis, or directly acquire and analyse baseband I and Q signals. It operates through a unique, intuitive model, passing the signal through a chain of user-defined processing blocks to simplify the most sophisticated analysis, the company indicated. Standard processing blocks include mixers, filters, phase estimators and equalisers. Users may also insert custom MATLAB processing blocks at any point in the processing chain.

VectorLinQ VSA offers various ways to analyse and view demodulated waveforms, stated the company. The I-Q constellation diagram helps identify signal quality issues such as amplitude imbalances, quadrature error and phase noise. Users may view I and Q components, amplitude, power, phase and EVM as "traces" in the time domain, time-correlated with other waveforms in the oscilloscope. Eye-diagram views of any trace provide deeper insight into the signal quality of demodulated waveforms. Spectral views of the total signal, as well as of the individual I and Q components, are also available as standard.

VectorLinQ VSA has a US list price of $10,000, and is available on Teledyne LeCroy WavePro 7Zi, WaveMaster 8Zi, LabMaster 9Zi and LabMaster 10Zi oscilloscopes running firmware version 7.9.x or later.
