Anritsu MU181800B – Clock Distribution Module; 14 GHz

The Anritsu MU181800B is a 14 GHz clock distribution module engineered as a plug-in card for the Anritsu Signal Quality Analyzer (SQA) platform. It generates and distributes five synchronized 1:1 clock channels derived from an external input clock, operating across 0.1 GHz to 14 GHz. This module is purpose-built for R&D and manufacturing environments where high-speed digital communication equipment demands precise timing and minimal jitter to maintain signal integrity.
