Agilent / Keysight N5249B PNA-X Microwave Network Analyzer 10 MHz to 8.5 GHz

The Keysight N5249B PNA-X is a 10 MHz to 8.5 GHz microwave network analyzer that integrates vector network analysis, spectrum analysis, noise figure measurement, and power metering into a single test engine. Two internal signal sources, dual receivers, and an internal signal combiner enable linear and nonlinear characterization of active devices - amplifiers, mixers, and frequency converters - from a single connection point to the device under test.
