Battery Operated RF Field Strength Meter with Spectrum Capability

AWT Global’s new UBA 9290 is battery operated, hand-held RF Field Strength Meter with spectrum capability. It is ideal for measuring various RF signals, and with a frequency range of 100 kHz to 2900 MHz, it is suitable for many applications in telecommunications, Cable TV, RFID, WiFi, and general analysis, service and maintenance of RF systems. The low noise floor of -117 dBm allows to detect and analyze even weak signals. With its basic spectrum analyzer functionality, the UBA 9290 is well suited for many applications in the field, laboratory and production. It provides engineers and technicians a cost-effective but powerful tool for RF signal analysis, and that at a fraction of the cost of a full-features conventional spectrum analyzer.

With its user friendly interface, the UBA 9290 is very easy to use. It allows to conveniently set measurements, but offers also 100 presets such as predefined range or channel settings and other special functions that are commonly used in analog communication systems. The analyzer supports high-speed USB and includes software that controls the instrument from a PC. Measurement data can be stored on the computer for further analysis.

The affordable handheld RF Field Strength Analyzer UBA 9290 is an ideal tool for field testing installing and maintaining mobile telecommunication systems such as cellular phones, Cable and Satellite TV Systems as well as performing antenna site measurements and maintenance.
