1Overview
The Model 805-SG is a compact microwave signal source that delivers low phase noise and fast switching across a wide span, from 8 kHz up to 20 GHz. A high-stability OCXO anchors the output, and the calibrated, phase-lockable signal makes the unit a practical drop-in where a benchtop generator is too large or too costly.
It serves as a direct substitute for National Instruments FSW and FSL sources and as a drop-in replacement for the obsolete QuickSyn synthesizers. The package is small enough to embed in automated test equipment, yet it supports portable battery operation for field deployment.
2Key Features
