Anritsu Option 128; Vector Signal Analysis Enabled (Requires Option 124 or 126)
The Anritsu MS27200A-3128 is Option 128 for the MS27200A Spectrum Master series. This option enables Vector Signal Analysis (VSA) capabilities on the instrument, allowing users to perform advanced modulation analysis and troubleshooting of complex wireless signals. Option 128 requires the prior installation of either Option 124 (IQ Data Capture) or Option 126 (Real-Time Spectrum Analyzer) to function. With VSA enabled, the MS27200A can demodulate and analyze a wide range of digital and analog signal formats, providing detailed measurements such as EVM, constellation diagrams, and spectrum displays. This enhances the instrument's utility for wireless communications testing, signal integrity verification, and interference analysis.
