Rohde & Schwarz ZNB4 Vector Network Analyzer
The Rohde & Schwarz ZNB4 is an advanced Vector Network Analyzer (VNA) specifically engineered to meet the rigorous demands of RF component development and production. With its remarkable dynamic range of up to 140 dB at a 10 Hz IF bandwidth and exceptional low trace noise of less than 0.004 dB RMS (at 10 kHz IF bandwidth), the ZNB4 is designed for precision in high-stakes environments.
This model covers a broad frequency spectrum from 9 kHz to 4.5 GHz, making it versatile for various applications in mobile radio and electronic goods industries. The instrument boasts a large, high-resolution 12.1-inch touchscreen that ensures seamless navigation through its comprehensive functions with no more than three operating steps. Users can easily access and display extensive measurement results clearly and efficiently.
Whether in a development lab or a production line, the R&S ZNB4 offers performance features typically reserved for higher-end analyzers. Available in both two-port and four-port configurations, it provides fast and accurate measurements with a high output power of up to +13 dBm, adjustable electronically over a substantial range of 90 dB. This capability helps to ensure improved throughput, crucial for high-volume production environments.
With measurement speeds surpassing 5 µs per point, the R&S ZNB4 VNA excels in both temperature and long-term stability, providing reliable measurements over extended periods without the need for recalibration. Its compact design, featuring low operational noise due to reduced power consumption and an innovative cooling concept, makes it a practical addition to any workbench. This low power consumption not only cuts operating costs but also contributes to environmental sustainability.
Designed for high-speed measurements on high-blocking filters or amplifiers, the ZNB4 is particularly beneficial in applications where efficiency is paramount. The analyzer's touchscreen interface enhances user experience, ideal for characterizing duplex filters, multiport devices under test (DUTs), mixers, or differential SAW filters for transmitters and mobile terminals.
