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.

– Typical Applications
Research and development of RF/microwave components and subsystems; manufacturing test of active devices; nonlinear device characterization; noise performance validation.
– Compatibility & Integration
Two internal signal sources, S-parameter and noise receivers, switch matrix, and digital voltmeter functionality eliminate the need for external instrumentation in many test scenarios.
