Rod and Schwartz have introduced four new R & s ZNL and R & s znle vector network analyzers, which can support operating frequencies up to 20 GHz. R & s economical vector network analyzer now covers the frequency required to study the second / third harmonic of products in 5 GHz and 6 GHz bands, such as WLAN or mobile wireless related products. The latest hardware version also includes a new option function to provide an internal CW signal generator for lower frequency R & s ZNL models.

R & s znl20 is one of the four new products of rod and Schwartz economical vector network analyzer.

R & s znl14, R & s znl20, R & s znla14 and R & s znla18. R & s ZNL model has dual port network analysis function, which can analyze full dual port s parameters from 5 kHz to 14 GHz and from 5 kHz to 20 GHz. The R & s znle model also has dual port network analysis function, which can analyze the full dual port s parameters from 100 kHz to 14 GHz and from 100 kHz to 18 GHz (over range 20 GHz).

Rod and Schwartz’s instrument is mainly aimed at the education, laboratory, production and automated testing markets. In these markets, the factors of cost performance, small size and product ease of use are the top priority. Like the time domain and fault distance analysis functions provided in the low frequency model, these four microwave models are also very suitable for signal and power integrity applications and cable and filter testing.

The operating frequency of most 5g FR1 applications is between 3-5 GHz, while wifi-6 (802.11ax) WLAN uses 6 GHz band. Its debugging in the design stage needs to cover the third harmonic, that is, the frequency up to 18-20 GHz. The R & s ZNL / znle series helps meet the growing demand for network analysis at these microwave frequencies at an attractive price.

R & s ZNL / znle is small and lightweight, easy to move between field applications and laboratories. ZNL is also equipped with an optional battery pack for field use. The user can use R & s ZNL / znle for measurement after opening the instrument with one key, without external display, laptop or additional software installation.

The new R & s ZNL is very suitable for commercial standards above 5 kHz. It can also carry out radiated emission measurement, including time domain scanning up to 18 GHz, so as to complete the measurement of on-site voltage standing wave ratio. R & s znl14 and R & s znl14 cover all frequencies of X-band and can be applied to various ground and airborne applications, including weather monitoring, air traffic control, military satellite transmission, positioning and target recognition.

R & s znl20 and R & s znle18 also support applications for measurements in the low K-band (KU), such as satellite point-to-point communication, television satellite broadcasting and return links for GNSS systems.

Low frequency model with independent internal CW source

The R & s znl-k14 option is included in the new version 1.41 hardware, and the functions of R & s znl3, R & s znl4 and R & s znl6 can be extended through the internal CW signal generator. The CW signal from port 1 can be used to excite the DUT, and the signal can be spectrum analyzed at port 2. This function needs to be based on the R & s znlx ‑ B1 spectrum analysis option.

R & s ZNL and R & s znle vector network analyzers are part of the R & s Essentials product catalog. New microwave models are now available from rod & Schwartz and designated distributors.
