Rohde & Schwarz ZNB4-R Vector Network Analyzer

Overview

The Rohde & Schwarz ZNB4-R Vector Network Analyzer is designed for demanding applications in the production and development of RF components, particularly in mobile radio and electronic goods industries. The ZNB4-R provides development labs and production lines with a wide dynamic range of 140 dB, low trace noise of 0.004 dB RMS and high output power of +13 dBm adjustable in a range of 90 dB. The analyzer combines high measurement accuracy with exceptional speed—better than 5 µs per point—and features excellent temperature and long-term stability ensuring reliable measurements for several days without recalibration.

The large 12.1-inch touchscreen allows access to all instrument functions in no more than three operating steps, displaying extensive measurements clearly and straightforwardly. The compact design and low operating noise make it ideal for both laboratory and production environments.
