The Advantest R3755A is a half-size PCI card network analyzer that brings vector measurement capability to embedded test systems and automated benchtop setups. Operating from 10 kHz to 300 MHz with 1 mHz resolution, it delivers precise characterization of impedance, gain, reflection, and frequency response across four measurement channels. The compact form factor (190 × 126 × 20 mm) and low power draw (15 W maximum) make it ideal for board-level diagnostics, educational labs, and OEM integration where space and cost constraints are critical.
