The Rohde & Schwarz ZNL6 is a two-port vector network analyzer spanning 5 kHz to 6 GHz, engineered for laboratory and production RF testing. It delivers 130 dB typical dynamic range, trace noise of 0.001 dB typical, and a noise floor of –140 dBm/Hz, enabling precise characterization of passive and active components. The instrument supports S-parameter, impedance, admittance, and stability factor measurements across multiple display formats including Smith chart, polar diagram, and time-domain analysis. A 10.1″ multitouch WXGA display and Windows 10 operating system streamline operation, while 1 Hz frequency resolution and IF bandwidth down to 1 Hz enable detailed spectral analysis. Compact dimensions (408 × 186 × 235 mm) and optional battery pack enable field deployment without sacrificing measurement integrity.
