Anritsu 37269D Vector Network Analyzer, 40 MHz – 40 GHz

The Anritsu 37269D is a 2-port vector network analyzer operating from 40 MHz to 40 GHz, engineered for S-parameter characterization across telecommunications, aerospace, defense, and RF component testing applications. It delivers fast measurement speeds under 5 ms per point with up to 1,601 discrete data points, supporting S11, S21, S22, S12, and custom a1/a2/b1/b2 combinations. The instrument combines high dynamic range - up to 115 dB at 2 GHz - with low noise floors reaching −107 dBm at 2 GHz and −97 dBm at 40 GHz, enabling precise phase and magnitude analysis across frequency, CW, and optional high-speed time-domain measurements.
