MUNICH – Rohde & Schwarz in Munich is introducing four R&S ZNL and R&S ZNLE vector network analyzers for mobile radio and wireless local-area network (LAN) applications. The test instruments are intended for automated testing, production, service lab, and education uses.
The R&S ZNL14, R&S ZNL20, R&S ZNLE14, and R&S ZNLE18 economy vector network analyzers have the frequency range necessary to investigate even third harmonics for 5 GHz and 6 GHz band technologies, and can support as many as 20 GHz of operation frequency.
The time-domain and distance-to-fault analysis options available in the lower frequency models are for signal and power integrity applications as well as cable and filter testing.
These test and measurement devices have two-port network analysis for component S-parameters from 5 kHz to 14 GHz, and 5 kHz to 20 GHz, and have two-port network analysis for S-parameters from 100 kHz to 14 GHz, and 100 kHz to 18 GHz (20 GHz in overrange).

The latest firmware release for these vector network analyzers also includes an option that provides lower frequency R&S ZNL models with an internal continuous-wave (CW) signal generator.
The light weight and small form factor make it easy to move the devices between test stations or labs. The ZNL also comes with an optional battery pack for field use. Users just push a button to switch on the instrument and start measuring with their ZNL or ZNLE. No external monitors, notebooks or additional software installations are needed.
The ZNL is for commercial standards of 5 kHz and upwards and can perform radiated emission measurements that include scans of as high as 18 GHz in the time domain to measure voltage standing wave ratios.
The ZNL14 and ZNLE14 cover all frequencies in the X band for commercial ground-based and airborne weather monitoring, air traffic control, military satellite transmissions, positioning and target identification.

The ZNL20 and ZNLE18 also support applications measuring in the lower K band (Ku), such as satellite point-to-point communications for GNSS systems, television satellite broadcasts and backhaul links.
The ZNL-K14 option is included in the 1.41 firmware release, expanding the ZNL3, ZNL4, and ZNL6 functions with an internal CW signal generator for DUT stimulation using a continuous wave signal from port 1, while the frequency spectrum is analyzed at port 2. The ZNLx-B1 spectrum analysis option is required for this function.
