The Anritsu 37217A is a Vector Network Analyzer delivering precision S-parameter measurements across 22.5 MHz to 8.6 GHz. Originally developed by Wiltron and now supported by Anritsu, this instrument characterizes RF components including amplifiers, filters, cables, and antennas with 130 dB dynamic range and measurement speeds of 16 µs/point. Four independent channels enable simultaneous S11, S21, S12, and S22 acquisition across up to 32,001 points, making it essential for R&D, production test, and quality control in RF laboratories.
