The Keysight (formerly Agilent) N5244A is a high-performance microwave vector network analyzer from the PNA-X series, covering a frequency range of 10 MHz to 43.5 GHz. Available in 2- or 4-port configurations, it is highly configurable with up to two built-in sources, an internal combiner, and signal-routing switches. It serves as a single-connection measurement solution for advanced active device characterization, including S-parameters, noise figure, gain compression, and intermodulation distortion (IMD), while offering pulse generation and millimeter-wave extension capabilities.
