The Anritsu 69337B is a low-noise synthesized signal generator delivering stable RF output across 2 to 20 GHz with exceptional phase noise performance for demanding radar, aerospace, and high-frequency communication applications. Ultra-low SSB phase noise of –107 dBc at 10 kHz offset enables critical signal integrity testing in development and production environments.
Technical Specifications
• Frequency Range: 2 GHz to 20 GHz
• Phase Noise: –107 dBc/Hz SSB at 10 kHz offset from 10 GHz
• Output Power: +17 dBm maximum; –125 dBm minimum; +17 dBm guaranteed leveled to 20 GHz
• Frequency Resolution: 1 kHz minimum step size (Option 11 provides 0.1 Hz)
• Internal Time Base Aging Rate: Typically <2 × 10⁻⁸/day; <5 × 10⁻¹⁰/day with Option 16
• Sweep Time Accuracy: Lesser of ±30 MHz or ±2 MHz for sweep speeds ≤50 MHz/ms
– Key Features
• Internal AM (0–90%, log or linear, DC to 100 kHz rates), FM (four modes to 10 MHz at 8 MHz rates or 100 MHz deviation at 100 Hz rates), phase, and pulse modulation
