Advantest R3753A – Network Analyzer, 5 Hz to 500 MHz

The Advantest R3753A is a vector network analyzer that characterizes electronic components and systems from 5 Hz to 500 MHz. It delivers precise measurements across frequency and time domains with a 115 dB dynamic range (1 kHz RBW), making it suitable for R&D, manufacturing, and quality control workflows. The instrument features three measurement channels, selectable 50 Ω or 1 MΩ/20 pF input impedance, and comprehensive S-parameter analysis including impedance, admittance, reflection, transmission, group delay, and phase measurements.
