The Anritsu 68137B Synthesized Sweep Generator delivers phase-locked signal generation across 2–20.0 GHz for RF and microwave component testing, system validation, and production environments. This instrument combines rapid frequency switching, ultra-low phase noise, and flexible sweep modes—including analog, step, manual, and alternate sweep configurations—with programmable frequency agility supporting up to 1000 non-sequential frequencies under GPIB control. Engineers rely on it for demanding test scenarios requiring low-distortion outputs and precise modulation control.

– Key Features
• Broad and narrow-band sweep modes with user-selectable step counts (1 to 10,000) or step sizes (1 kHz to full range)
• Sweep width independently selected from 1 kHz to full frequency range
• Alternate sweep mode: sweeps between two ranges with independent power levels per range
• Manual sweep mode: phase-locked frequency stepping with user-configurable steps
• Programmable frequency agility: addresses up to 1000 stored frequencies as phase-locked step sweep
• Internal AM, FM, phase modulation, and pulse modulation with swept delay
• External AM (log or linear) and external FM (locked or unlocked)
• Flexible pulse triggering: free-run, delayed, gated, and composite modes
• Front-panel control with GPIB remote interface
– Typical Applications
• Component and subsystem testing across X, Ku, and K bands
• System validation and characterization
• Automated production test and burn-in
• Radar and satellite signal simulation
