The Astronics / EADS / Racal 3161 is a single-slot VXIbus waveform synthesizer delivering 300 MS/s sampling for high-fidelity arbitrary waveform generation across aerospace, defense, and telecommunications applications. The instrument generates complex signals from 100 µHz to 150 MHz with 12-bit resolution and supports real-time frequency hopping between 256 programmable frequencies, external modulation inputs (AM, PM, FSK), and phase-coherent synchronization to external analog signals up to 18.75 MHz.
## Technical Specifications
• Sampling Rate: 300 MS/s
• Output Frequency Range: 100 µHz to 150 MHz
• Resolution: 12-bit
• Waveform Memory: 256k points standard; 1 Meg points optional
