Anritsu MS46322B – Economy Vector Network Analyzer

The Anritsu MS46322B is a 2-port Vector Network Analyzer built on patented ShockLine VNA-on-chip technology. It delivers fast, accurate S-parameter and time-domain measurements across three configurable frequency bands, from 8 GHz to 43.5 GHz. The MS46322B balances performance and cost, making it ideal for RF/microwave component characterization, manufacturing test, and educational environments.

Technical Specifications

Frequency Coverage
Three models support 1 MHz to 8 GHz, 1 MHz to 20 GHz, or 1 MHz to 43.5 GHz operation. S-Parameter & Time-Domain Measurements
Full 2-port capability: S11, S12, S21, S22. Time-domain option (MS46322B-002) enables time gating for rapid fault identification. Measurement speed reaches 130 µs per point. Dynamic Performance
