Anritsu 37247C Vector Network Analyzer, 20GHz

The Anritsu 37247C is a 20 GHz vector network analyzer designed for S-parameter characterization of RF and microwave components. It combines a synthesized source, integrated S-parameter test set, and four-channel receiver in a single benchtop instrument. The 37247C delivers dynamic range exceeding 100 dB with measurement accuracy of ±0.05 dB (typical) and supports fast, 12-term error-corrected sweeps with measurement update rates under 2 ms per point.
