Agilent E5100B 300MHz High-Speed Network Analyzer

The Agilent E5100B is a 300 MHz high-speed network analyzer engineered for precise low-frequency impedance and S-parameter measurements across R&D and production environments. Operating from 10 kHz to 300 MHz, the instrument delivers sweep speeds as fast as 0.04 ms/point and dynamic range exceeding 100 dB, making it ideal for high-throughput component characterization.

Key Features

• High dynamic range performance enables detection of weak signals and loss measurement in complex networks


• Configurable IF bandwidth from 10 Hz to 30 kHz optimizes measurement speed versus noise performance


• Four-channel architecture supports multi-port device characterization


• Extended output power range option (–48 dBm to +22 dBm) addresses low-level and high-power applications


• Parallel I/O (TTL, 16-bit output, 8-bit input/output) with optional opto-isolation for production integration


• IBASIC programming support with floppy disk and non-volatile memory storage

Typical Applications Filters, resonators, matching networks, and transmission-line characterization in manufacturing and design validation. Fast sweep times enable high-volume production testing of passive and active RF components.
