The Keysight N5242B PNA-X is a microwave network analyzer covering 10 MHz to 26.5 GHz with configurable 2-port or 4-port architecture. It integrates dual internal signal sources, a signal combiner, S-parameter and noise receivers, pulse modulators, and flexible RF switching—eliminating the need for multiple instruments in a single test connection. The instrument delivers up to 134 dB dynamic range at 20 GHz with trace noise of 0.002 dB rms at 1 kHz bandwidth. Measurement speed ranges from 3.6 to 23 μsec/point, while thermal stability holds ±0.03 dB/°C. Source output power reaches +13 dBm at 1 GHz declining to +11 dBm at 67 GHz, with harmonics suppressed to −60 dBc.
