A New Switched Attenuator Architecture for Reduced Uncertainty

Scale fidelity (or log conformance) calibration of high performance spectrum analyzers and an increasing demand for linearity verification of power sensors are strong drivers for reduced attenuation measurement uncertainties. The achievable performance of a precision RF and microwave switched attenuator is typically compromised by its mismatch and the source, load and transmission line mismatch conditions around it.

This webinar presents how a novel signal leveling and switching architecture, integrated within a purpose designed RF Reference source, has significantly reduced mismatch and its potential impact. Also discussed are the results achieved and the quantified benefits for traceability import and export.
