Anritsu MS2035B – VNA Master / Spectrum Analyzer; 500 kHz – 6 GHz / 9 kHz – 6 GHz

The Anritsu MS2035B is a dual-function Vector Network Analyzer and Spectrum Analyzer delivering integrated RF characterization across 500 kHz to 6 GHz (VNA) and 9 kHz to 6 GHz (SA). This 2-port instrument combines S-parameter measurement, return loss, insertion loss, VSWR, and impedance analysis with broadband spectrum monitoring, making it suitable for base station commissioning, component validation, and field troubleshooting.
