The Rohde & Schwarz ZVRE is a vector network analyzer engineered for amplitude and phase measurement of S-parameters, Z-parameters, and Y-parameters across 1-port and 2-port electrical networks. This economy-class instrument integrates a generator, test set, and receiver in a single chassis, delivering high measurement accuracy with dynamic range exceeding 125 dB. The ZVRE features two SWR bridges, an RF switch, two measurement channels, and one reference channel, enabling full two-port calibration (TOSM) and automatic calibration (AutoKal). Measurement speed reaches <125 µs/point normalized or 25 sweeps/s with 200 points. A 26 cm color LCD display provides real-time trace visualization and control.
