Rohde & Schwarz ZVL3-75 Vector Network Analyzer

The Rohde & Schwarz ZVL3-75 is a 75 Ohm vector network analyzer engineered for RF component characterization, TV/CATV system analysis, and general network measurement. Operating from 9 kHz to 3 GHz, this portable instrument integrates network analysis, spectrum analysis, and power measurement into a single platform, delivering dynamic range exceeding 115 dB (typical 123 dB) with measurement bandwidths up to 500 kHz for fast, accurate testing in development, production, and field service environments.

– Technical Specifications

– Key Features

• Complete S-parameter measurements with full system error correction via two-port bidirectional analysis
• Passive component characterization: impedance of filters, cables, and transmission line structures
• Active device measurements: amplifier and antenna matching assessment
• Time domain analysis and distance-to-fault (TDR) capability for cable fault detection
• Wide measurement bandwidth with fast synthesizers ensures high measurement throughput without sacrificing accuracy
• Multitrace display accommodates up to 100 simultaneous traces and diagrams
• Intuitive operator interface: front-panel keys, mouse/keyboard control, context-sensitive wizards, and undo/redo for up to six steps

– Optional Measurement Expansion

Spectrum Analysis (R&S ZVL-K1 option): Channel power, adjacent channel power, occupied bandwidth, CCDF measurement, and 20 MHz I/Q demodulation bandwidth. Spectrogram capability with R&S FSL-K14 option.

Power Measurement: Integration with external R&S NRP-Z power sensor series converts the instrument into a three-in-one network analyzer, spectrum analyzer, and power meter.
