Anritsu 37277B Vector Network Analyzer (40 MHz to 50 GHz)

The Anritsu 37277B is a benchtop vector network analyzer delivering S-parameter measurements from 40 MHz to 50 GHz. It integrates a synthesized source, S-parameter test set, and tuned receiver into a compact platform optimized for passive device characterization in both R&D and production environments. The instrument combines fast measurement speeds with full 12-term error correction, making it suitable for demanding RF and microwave testing applications.
