Agilent 8720A 130MHz-20GHz Microwave Network Analyzer w 001 and 10 W CALIBRATION

The Agilent 8720A is a microwave network analyzer operating from 130 MHz to 20 GHz, delivering S-parameter and vector network measurements with dynamic range exceeding 85 dB (up to 103 dB with variable-bandwidth IF filters). The instrument integrates a swept synthesized source, switching S-parameter test set, and dual independent display channels. Option 001 provides 1 Hz frequency resolution beyond the standard 100 kHz. With built-in vector accuracy enhancement, error correction, and time-domain capabilities, the 8720A characterizes impedance, transmission, reflection, magnitude, phase, group delay, and absolute power across RF and microwave devices. Its switching test set measures all four S-parameters from a single connection, while flexible data handling via external disk drive and HP-IB programmability supports R&D, manufacturing, incoming inspection, and quality assurance workflows.
