The Anritsu MU181000B is a four-port synthesizer module that generates precise clock signals from 0.1 GHz to 12.5 GHz for high-speed digital communication testing. Installed as a plug-in component in Anritsu Signal Quality Analyzer mainframes (MP1800A, MP1900A, MT1810A), this module delivers stable, low-jitter outputs across four independent ports with user-selectable frequency resolution of 1 kHz or 1 MHz. Output levels range from 0.4 Vp-p to 2 Vp-p AC, with frequency stability of ±1 ppm when using the internal reference clock.
Technical Specifications
• Frequency Range: 0.1 GHz to 12.5 GHz
• Setting Resolution: 1 kHz or 1 MHz (switchable)
• Frequency Stability: ±1 ppm (internal reference)
• Offset Function: −1000 to +1000 ppm, 1 ppm steps, 1 Hz minimum resolution
• Output Ports: 4 independent channels

– Key Features
• Four synchronized output ports eliminate the need for external distribution amplifiers in multi-channel test setups
• Offset capability enables precise frequency deviation testing from −1000 to +1000 ppm
• Optional jitter modulation support (Option MU181000B-001 or retrofit Option MU181000B-101) enables dual-tone SJ, RJ, BUJ, and SSC modulation with half-period jitter (even/odd) support
• 1 kHz resolution at lower frequencies; 1 MHz switchable mode for faster swept-frequency measurements
• Includes four 0.3 m SMA coaxial cables (DC to 18 GHz) as standard
– Typical Applications
Clock distribution and frequency offset generation for stress testing high-speed serial I/O, timing characterization in digital communication systems, and jitter tolerance analysis when equipped with modulation options.
– Compatibility & Integration
Plug-in module for Anritsu Signal Quality Analyzer Series mainframes. Direct compatibility with MP1800A, MT1810A, and MP1900A platforms. Optional PCIE Reference Clock module (Option MU181000B-002) available for external reference synchronization.
