The Rohde & Schwarz ZVL6 is a portable vector network analyzer that combines network analysis, spectrum analysis, and power measurement in a single compact instrument. Operating from 9 kHz to 6 GHz, it delivers dynamic range exceeding 115 dB (typically 123 dB) across most of its frequency span, with measurement times under 75 ms for full two-port calibrated S-parameter data. The instrument weighs less than 7 kg and supports battery operation, making it suitable for laboratory, development, production, and field service applications.
