Rohde & Schwarz ZNB20 Vector Network Analyzer
The Rohde & Schwarz ZNB20 Vector Network Analyzer (VNA) is engineered for precision and efficiency in the challenging environments of RF component development and production. With a frequency range spanning from 9 kHz to 20 GHz, this advanced analyzer features remarkable performance characteristics that support demanding applications in mobile radio and electronic goods industries.
Key to its exceptional capabilities is its wide dynamic range of up to 140 dB (measured at 10 Hz IF bandwidth) and low trace noise of less than 0.004 dB RMS (at 10 kHz IF bandwidth). The ZNB20 also boasts high output power of up to +13 dBm, easily adjusted electronically across a range exceeding 95 dB, ensuring fast and accurate measurements for enhanced throughput in production lines.
Designed with user convenience in mind, the ZNB20 features a large 12.1-inch high-resolution touchscreen that allows effortless access to instrument functions, typically requiring no more than three operating steps. This ergonomic interface displays extensive measurement results clearly, facilitating rapid analysis and decision-making.
Available in both two-port and four-port configurations, the Rohde & Schwarz ZNB20 sets a new standard by combining high measurement accuracy with exceptional speed—notably achieving better than 5 µs per point. Its impressive thermal stability, typified by a stability of 0.01 dB/°C, ensures consistent and reliable measurements over extended periods without needing recalibration. The compact design of the device minimizes workspace occupancy while maintaining low operating noise due to efficient power consumption and advanced cooling solutions.
Ideal for high-volume production settings, the ZNB20 excels in characterizing challenging components such as duplex filters and amplifiers, particularly where manual adjustments are essential. The versatile nature of this VNA also allows it to effectively characterize multiport DUTs, mixers, and differential SAW filters used in transmitters and mobile terminals.
