The system design is based on cascaded filter units, with up to six filters for different frequency bands that can be connected to each base unit. The filters are field-replaceable and operate on a plug-and-play concept, minimizing changeover times. Automatic band switching makes the system particularly suitable for production environments involving frequent frequency band changes.
The new generation offers high measurement speeds, a wide frequency bandwidth, and precise analysis functions. The integrated Distance-to-PIM (DTP) function enables quick and accurate identification of interference sources, significantly accelerating the fault diagnosis process.
Broadband VNA functionality is available as a hardware option directly on the same test port. This enables precise localization of VSWR mismatches. Consequently, users can efficiently perform PIM measurements and vector network analysis with a single system, eliminating the need for additional test equipment.
Multiport and Multifrequency Testing Solution
To complement the rack solution, Rosenberger offers a multiport analyzer configuration that enables simultaneous testing across multiple ports and frequency bands. Several base units and filters connect directly to the device under test via a combiner unit. This configuration reduces the number of connector cycles and significantly shortens the overall test time.
PIM testing equipment is essential for ensuring the quality of modern mobile networks. Passive intermodulation, which arises from nonlinear effects in RF components, can cause interference in the form of reduced data rates or unstable connections. Therefore, accurate measurement and analysis technology is essential for detecting and addressing such effects at an early stage.
