ADVANTEST R3763B NETWORK Analyzer 300kHz - 3.6GHz

The Advantest R3763B is a vector network analyzer operating across 300 kHz to 3.6 GHz, engineered for high-accuracy characterization of RF components and networks in development, manufacturing, and research environments. It delivers transmission and reflection measurements (S11, S21) with amplitude resolution of 0.001 dB and phase resolution of 0.01°, supported by fast 0.5 ms per-point measurement speed. The instrument integrates a built-in BASIC controller for autonomous measurement, analysis, and data processing - eliminating external computer dependencies and accelerating ATE integration.

Directivity exceeds 35 dB across 20 MHz to 2.0 GHz, while amplitude and phase tracking maintain 0.5 dB and 15° accuracy respectively.
