The R&S ZNB and R&S ZNC vector network analyzers from Rohde & Schwarz feature a dynamic range up to 140 dB, a sweep time of 4 ms with 401 points.
They are designed for applications in the production and development of RF components, particularly in the mobile radio and electronic goods industries.
The network analyzers cover the frequency ranges from 9 kHz to 3 GHz, 4.5 GHz or 8.5 GHz. Both the R&S ZNB and the R&S ZNC have a touchscreen that allows users to access all instrument functions with no more than three operating steps.
The more powerful of the two instruments is the R&S ZNB which covers the frequency range from 9 kHz to 4.5 GHz or 8.5 GHz and is available both in two-port and four-port models. Its dynamic range is 140 dB, trace noise is 0.004 dB (RMS) and output power is up to +13 dBm, which can be adjusted electronically in a range of 90 dB.
The R&S ZNB is suited for measurements on high-blocking filters or amplifiers that must be manually adjusted on high-volume production lines where speed and efficiency are critical. The network analyzer can also be used to characterize duplex filters, multiport DUTs, mixers or differential SAW filters for transmitters or mobile terminals.
The R&S ZNC with a frequency range from 9 kHz to 3 GHz is available with two test ports and offers a sweep time of 11 ms with 401 points and a dynamic range of up to 130 dB. Its primary use is for testing passive RF components such as filters or cables.
Instead of using submenus or nested menus, all context-based control elements are directly available on the soft panel. The user interface and online help are available in English as well as Chinese, Japanese, French and Russian.
The R&S ZNC (two test ports, up to 3 GHz) and the R&S ZNB (two test ports, up to 4.5 GHz and 8.5 GHz) are now available from Rohde & Schwarz. As of September 2011, the two R&S ZNB models will be available with four ports.
