Agilent/Keysight M9375A

The Keysight M9375A is a PXIe vector network analyzer delivering full two-port VNA capability within a single PXI slot. Engineered for automated test systems where space and integration are paramount, it combines RF and microwave measurement capability with modular flexibility. The M9375A operates standalone or cascades with additional modules to create multiport configurations supporting up to 32 ports, enabling efficient characterization of components across demanding frequency ranges.
