Teledyne LeCroy adds vector signal analysis software to oscilloscopes

Test and measurement instrument house Teledyne LeCroy has unveiled a vector signal analysis software option for its oscilloscopes to help assess complex modulation formats. The VectorLinQ vector signal analysis software option enables visualization and analysis of such modulation formats as n-PSK, n-QAM, circular QAM, ASK, and FSK, as well as custom signal types and symbol positions.

VectorLinQ software enables demodulation of RF signals for analysis or the direct acquisition and analysis of baseband I and Q signals, according to Teledyne LeCroy. The software helps pass the signal under test through a chain of user-defined processing blocks, which simplifies even the most sophisticated analysis, the company asserts. Standard processing blocks include mixers, filters, phase estimators, and equalizers. Users also can insert custom MATLAB processing blocks at any point in the processing chain.

VectorLinQ's I-Q constellation diagram feature helps identify signal quality issues such as amplitude imbalances, quadrature error, and phase noise. Users can view I and Q components, amplitude, power, phase, and error vector magnitude (EVM) as "traces" in the time domain, time-correlated with other waveforms in the oscilloscope. Eye-diagram views of any trace of the demodulated waveform are possible as well. Spectral views of the total signal, as well as of the individual I and Q components, are also available as standard.

Users can implement the software package on Teledyne LeCroy WavePro 7Zi, WaveMaster 8Zi, LabMaster 9Zi and LabMaster 10Zi oscilloscopes running firmware version 7.9.x or later. VectorLinQ has a U.S. list price of $10,000, and is available now.
