The Anritsu 68187B Synthesized Sweep Generator is a microprocessor-based signal source spanning 0.01 to 60.0 GHz, engineered for RF and microwave component characterization, local oscillator replacement, and automated test systems. It delivers phase-locked output across multiple sweep architectures—analog, step, manual, and alternate modes—with output power ranging from -125 dBm to +17 dBm. Ultra-low SSB phase noise and programmable frequency agility supporting up to 1000 non-sequential frequencies enable precise signal simulation and measurement.
Technical Specifications
• Frequency Range: 0.01 to 60.0 GHz, phase-locked across all sweep modes
