The Keysight P5025A is a 4-port vector network analyzer for high-performance RF and microwave characterization from 100 kHz to 26.5 GHz. This USB-controlled instrument delivers 137 dB dynamic range and -129 dBm noise floor, enabling precision measurement of components, signal integrity, and radar cross-section performance. The analyzer employs twelve-term vector error correction to remove systematic errors across frequency-dependent effects, directional coupler imperfections, source match, reflection tracking, and impedance mismatch. Its compact form factor (176 × 68 × 333 mm) houses three 3.5 mm female ports and one MCX port, all 50 Ohm impedance.
