Anritsu 69137A Synthesized Sweep Generator, 2 – 20.0 GHz

The Anritsu 69137A is a synthesized sweep generator delivering phase-locked RF signal generation across 2 to 20 GHz. Built for precision RF measurements and component characterization, it combines ultra-low SSB phase noise with flexible sweep architecture and programmable frequency agility—making it essential for signal integrity analysis, ATE systems, and laboratory-grade signal simulation.

– Technical Specifications

Frequency Range: 2 to 20 GHz

Output Power: +17 dBm maximum; −125 dBm minimum

Phase Noise (SSB): −100 dBc/Hz at 10 kHz offset (referenced at 10 GHz)

Sweep Modes:
• Analog sweep across selected frequency ranges
• Step sweep: 1 to 10,000 steps with phase-locking at each step; minimum step size 1 kHz (0.1 Hz with Option 11)
