Scalar Network Analyzer, Migrating from Scalar to Vector Network Analyzer Systems

The Keysight 8757D scalar network analyzer allows you to measure insertion loss, gain, return loss, SWR, and power quickly and accurately . With high-performance detectors and directional bridges, and a companion Keysight source and printer, this analyzer becomes the basis of a complete measurement system with superb performance.

Setup time is reduced by external disk save/recall, and measurement data can be sent directly to a printer while you proceed to the next measurement.

You can configure your system using a Keysight PSG signal generator with ramp sweep capability. The dynamic range can be extended from 75 dB to 83 dB using the PSG's high power option.
