37397C

The Anritsu 37397C is a high-performance Vector Network Analyzer (VNA) within the 37300C "Lightning" series, covering a broad frequency range of 40 MHz to 65 GHz. It integrates a synthesized microwave source, a complete S-parameter test set, and a tuned receiver into a single instrument. Optimized for active device characterization, the 37397C features built-in step attenuators, internal bias tees, and advanced measurement capabilities such as frequency offset and time domain analysis.
