Premium Benchtop Performance: ZNB and ZVA Families
The Rohde & Schwarz ZNB and ZVA series represent the high-performance tier of the manufacturer's network analyzer range. Within the ZNB family, instruments like the Rohde & Schwarz ZNB4 (9 kHz to 4.5 GHz), Rohde & Schwarz ZNB8 (9 kHz to 8.5 GHz), and Rohde & Schwarz ZNB20 (100 kHz to 20 GHz) feature 12.1-inch high-resolution touchscreens and flexible port configurations, available in 2-port and 4-port options. These benchtop units are designed for demanding RF component development, production, and service environments.
For more complex active component characterizations, the ZVA series provides enhanced hardware flexibility. The Rohde & Schwarz ZVA24 (10 MHz to 24 GHz) and Rohde & Schwarz ZVA40 (10 MHz to 40 GHz) utilize a dedicated multi-port architecture featuring one reference receiver and one measurement receiver for each individual port. This architecture enables pulsed RF capabilities and true differential measurements, which are option-dependent and critical for advanced microwave and millimeter-wave design verification.
Portability and Field Integration with the ZVL Family
For field deployments, installation work, or space-constrained labs, Rohde & Schwarz provides compact solutions such as the Rohde & Schwarz ZVL13. Operating from 9 kHz to 13.6 GHz, this bidirectional two-port network analyzer weighs less than 7 kg. It is built for versatility, supporting optional battery power and an optional spectrum analysis extension (R&S ZVL-K1) to perform both network and signal analyses inside a single instrument. The unit features N-type female connectors and a 6.5-inch color VGA screen.
Legacy Systems: The ZV Family
The established Rohde & Schwarz ZVR and Rohde & Schwarz ZVC systems belong to the classic ZV family of vector network analyzers. Operating on a Windows NT platform, these dual-port instruments are optimized for fundamental RF measurements. The Rohde & Schwarz ZVR covers a wide frequency sweep from 10 Hz to 4 GHz, while the Rohde & Schwarz ZVC spans 20 kHz to 8 GHz. Both models feature an N-type female test port interface, weigh 27 kg, and deliver a system dynamic range exceeding 130 dB at a 10 Hz IF bandwidth, ensuring highly stable measurements for legacy automated test environment (ATE) setups.
