The FieldFox high-performance Vector Network Analyzer from Keysight offers the precision of a benchtop RF and microwave analyzer in the industry’s most integrated handheld unit. This network analyzer with (optional) spectrum analyzer can measure up to 50GHz. Compact size of only 11.5” (H) x 7.4” (W) x 2.8” (D), this lightweight unit weighs approximately 7lbs and provides battery life of up to 3-1/2 hours, allowing easy transportation and placement close to the object to be measured, achieving more efficient characterization. While designed for outdoor use, its high performance makes this unit completely suitable in R&D applications in the lab or on the bench. The base function of the FieldFox RF Combination Analyzer is a cable and antenna analyzer which can be configured to include a spectrum and network analyzer. Optional capabilities include power meter, independent signal generator, vector voltmeter, interference analyzer, variable DC source, and GPS receiver.
