The Anritsu 69387A is a synthesized sweep/signal generator delivering precise signal generation from 0.01 GHz to 60 GHz. Built for RF/microwave system analysis and validation, it combines ultra-low phase noise with rapid frequency tuning and sophisticated modulation capabilities. The instrument executes complex measurement scenarios through step and analog sweep modes, pulse modulation with configurable waveforms, and synchronized multi-modulation control.
Technical Specifications
Frequency Range: 0.01 GHz to 60 GHz
Tuning Speed: Typically less than 40 ms to settle within 1 kHz of final frequency. Step sweep maximum switching time is less than 15 ms + 1 ms/GHz step size, or less than 40 ms, whichever is smaller.
Phase Noise: Ultra-low SSB phase noise at -100 dBc (10 kHz offset from 10 GHz).
Time Base Accuracy: Stability depends on 10 MHz reference. Aging: < 2 × 10⁻⁸/day standard (< 5 × 10⁻¹⁰/day with Option 16). Temperature stability: < 2 × 10⁻⁸/°C across 0°C to 55°C (< 2 × 10⁻¹⁰/°C with Option 16).
Reference Output: 10 MHz reference, 0.5 V p-p into 50 Ω, AC coupled, rear-panel BNC.
