Advantest R3753XH – Network analyzer

The Advantest R3753XH is a network analyzer engineered for vector characterization of electronic networks across 2-port, 3-port, and 4-port device configurations. It delivers S-parameter measurements with simultaneous 2-channel 4-trace capability and supports parameter conversion to impedance (Z) and admittance (Y) formats, making it essential for RF device development, component qualification, and manufacturing test environments.
