Logic analyzers do vector signal analysis
Staff -- Test & Measurement World, 3/1/2006
Agilent Technologies has integrated its logic analyzers with the company's 89600 Series VSA (vector signal analysis) software. The company describes the resulting combination as a digital vector-signal-analysis system that delivers precise, accurate modulation measurements on the digitized communication signals found in DSP-based radio transceivers used in cell phones, base stations, satellite and military communications systems, and radar applications.
Running on Agilent 1680, 1690, and 16900 series logic analyzers, the Digital VSA software provides analysis of digital base-band or digital IF signals in a variety of formats, including scalar base band, scalar IF, complex I/Q, magnitude and phase, and phase only. It also permits flexible demodulation that measures carrier offset, error vector magnitude (EVM), and frequency error for QPSK, QAM, GSM, EDGE, WiMAX, W-CDMA, and others. Finally, it supports multiple display formats, including phase vs. time, frequency vs. time, and spectrogram.
Base price for the addition of the Digital VSA software to a logic analyzer: $10,000. Agilent Technologies, www.agilent.com.
