Anritsu MS2028C – VNA Master; 2-Port, 5 kHz to 20 GHz

The Anritsu MS2028C is a portable 2-port Vector Network Analyzer operating from 5 kHz to 20 GHz, engineered for field-deployed RF and microwave characterization. It delivers all four S-parameters (S11, S21, S22, S12) from a single connection with 350 µs measurement speed per data point and up to 4,001 points per trace. Dynamic range extends to 100 dB with maximum 106 dBm capability. The instrument employs 12-term error correction and supports reciprocal calibration methods (SOLR, SSLR, SSSR) to enable high-accuracy measurements of cables, antennas, filters, and passive components across demanding environments.
