The Anritsu MS4647B is a 2-port vector network analyzer delivering S-parameter, pulse, and intermodulation measurements across 10 MHz to 70 GHz. This platform supports dynamic range to 142 dB, output power to +14 dBm, and measurement speeds of 20 µs per point with up to 100,000 points on graph. Port directivity, source match, and load match each reach 50 dB. The MS4647B expands to 4-port capability via external measuring units and supports optional low-end frequency extension down to 70 kHz.
