The R&S ZNL20 is one of four new microwave models of the Rohde & Schwarz economy VNAs. The economy VNAs now have the frequency range necessary to investigate even third harmonics for 5 GHz and 6 GHz band technologies, such as wireless LAN or mobile radio. The latest firmware release also includes a brand-new option that provides lower frequency R&S ZNL models with an internal CW signal
Four new portable benchtop vector network analyzers are now available from Rohde & Schwarz: The R&S ZNL14, R&S ZNL20, R&S ZNLE14 and R&S ZNLE18. The R&S ZNL models have two-port network analysis for a complete set of component S-parameters from 5 kHz to 14 GHz and 5 kHz to 20 GHz.
The R&S ZNLE models have two-port network analysis for a complete set of S-parameters from 100 kHz to 14 GHz and 100 kHz to 18 GHz (20 GHz in overrange).
The Rohde & Schwarz instruments are intended for the education, service lab, production and automated testing markets where a balanced price/performance ratio, a small size factor and ease-of-use are top priorities. Together with the time-domain and distance-to-fault analysis options available in the lower frequency models, the four microwave models are ideal for signal and power integrity applications as well as cable and filter testing.
Most 5G FR1 applications use frequencies between 3 and 5 GHz; while wireless LAN for WiFi-6 (802.11ax) uses the 6 GHz band. Debug trials in the design stage need to include the third harmonic, or frequencies up to 18 and 20 GHz. The Rohde & Schwarz instruments in the R&S ZNL/ZNLE family help meet the increasing demand for network analysis at these microwave frequencies and have an attractive price.
