UbiNS UBA-9290 RF Field Strength Analyzer

UbiNS UBA-9290 RF Field Strength Analyzer

The UBA-9290 is a portable RF Field Strength Analyzer with spectrum capability. It is the ideal instrument for measuring  RF signals within a frequency range of 100 kHz to 2.9 GHz. 

The UBA-9290 is designed for various applications related to the general analysis, maintenence and service of RF systems including cable tv, RFID, Telecommunications, TV cell phone equipment and WiFi. The low noise floor of -117 dBm allows the user to observe and analyze even weak signals. The UBA-9290's basic spectrum analyzer capabilities makes it well suited for many field applications, laboratory use and even on the production line.  

This is a cost effective and powerful tool for engineers, scientists and technicians involved in RF signal analysis available for a fraction of the cost for a full featured standard spectrum analyzer.

This Field Strength Analyzer features a user friendly interface making it quite easy to use. Settings and measurements are conveniently set and it also allows for 100 user defined presets such as predefined ranges or channel settings and other special functions that are frequently used in communication systems. This frequency analyzer supports high speed USB and ships with software that allows the user to control the UBA-2900 from a Personal Computer. Measurements may be stored on the P.C. for additional analysis.
