The Anritsu 37225A is a vector network analyzer delivering S-parameter and vector network analysis across 22 MHz to 13.3 GHz. Built as a single-instrument system, it combines an integrated fast-sweeping synthesized source, auto-reversing S-parameter test set, and 4-channel receiver to characterize RF and microwave components during design, manufacturing, and quality assurance workflows. The instrument supports multiple measurement formats—log magnitude, phase, Smith chart (impedance and admittance), log polar, group delay, and linear magnitude—with up to 1601 data points and six independent markers. A 7.5″ color display with user-definable trace text and graticule colors provides immediate visualization of results.
