Paper Abstract

An Offset Generator with low noise floor has been developed by Time & Frequency Measurement & Control Department, NTSC. The Offset Generator is designed with Phase Lock Loop, and the +100Hz offset is generated in the output stage. The Allan deviation noise floor of the Offset Generator is 1x10-12 at 1 second. The Offset Generator has been installed in "Digital Multi-Channel Frequency Stability Analyzer" (DFSA), developed by Time & Frequency Measurement & Control Department, NTSC, too, and the Allan deviation noise floor of DFSA using current Offset Generator is about 4x10-14 at 1 second and <1x10-15 at 1000 second.
