Keysight N5245B, part of the PNA‑X series, goes far beyond a standard vector network analyzer. It’s a highly integrated, versatile microwave measurement platform designed for testing active components like amplifiers, mixers, and frequency converters. Its architecture incorporates dual internal signal sources, a built‑in combiner, S‑parameter and noise receivers, pulse modulation and generation capabilities, plus an array of switches and RF access points. Together, these elements create a powerful foundation for performing a wide range of linear and nonlinear measurements—all through a single, consistent connection to your device under test.

About Option 423

Option 423 includes a combiner, mechanical switches, and more access loops. The internal second source provides an additional signal (fixed or swept) for two-tone intermodulation testing of amplifiers, or for use as a local oscillator for testing mixers and frequency converters. The mechanical switches switch the combiner in and out as needed, as well as enabling the additional access loops for advanced configurations. The second source drives ports 3 and 4 and is also available from port 1 when combined with source 1, or via rear-panel (N5241/42/44/45/49B) or front-panel (N5247B) access loops. The bias tees are connected directly to the test port couplers, which limits the maximum power rating on the pair to +30 dBm (additional attenuators or isolators are typically required to protect other components inside the instrument).

To independently control the frequency of the second internal source, one of the following software applications is required: S93080/029/070x/082/083/084/086/087/089/090x/093/094B or S94510/511B.
