Agilent Technologies Inc. recently introduced an innovative measurement solution that provides precise modulation measurements on the digitized communication signals found in the digital-signal processor-based radio transceivers used in cell phones, base stations, satellite and military communications systems, and radar applications. The Digital VSA solution integrates Agilent’s logic analyzers with its 89600 Series vector signal analysis software, which analyzes radio frequencies (RF). It allows digitized transmit-and-receive signals found on data buses between the baseband and radio-frequency blocks of digital-radio applications to be analyzed in the time, frequency and modulation domain, as if they were in full analog form. This allows an unprecedented view into circuit behavior at the digital interface between the baseband and RF-integrated circuits.
