Description
High-speed, agile RF generation for precision optical control and quantum systems
The XRF RF synthesizer from Santec is a high-performance, multi-channel RF source designed for advanced optical and quantum experiments. It combines ultra-fast frequency agility with precise amplitude, phase, and frequency modulation, enabling complex waveform generation for AOM control, laser stabilisation, and quantum manipulation.
Built around FPGA-driven DDS architecture, the XRF delivers exceptional flexibility and stability in a compact, robust platform suitable for both laboratory and experimental research environments.
Dual-channel high-power RF output
Two independent channels covering 20-400MHz, with up to 4W (+36dBm) output power.
Extended low-frequency operation
Frequency range extends down to 15kHz for low-power precision applications.
Advanced waveform generation
Supports complex FM/AM/PM sequences with interpolation, loops, ramps, and external triggers.
FPGA-based DDS architecture
Dual AD9910 DDS cores enable precise timing control with high resolution and stability.
Integrated servo and feedback control
Built-in PID functionality enables laser noise suppression and optical stabilisation (“noise-eating”).
Full computer control and automation
Ethernet/USB interface supports full parameter control and programmable sequence playback via Python, MATLAB, and LabVIEW.
Applications
- Optical lattice and quantum gas experiments
- Acousto-optic modulation (AOM) control
- Laser frequency stabilisation and noise suppression
- Coherent manipulation of atomic systems
- Complex waveform and pulse sequence generation
System Integration
The XRF can function as a standalone RF source or integrate into larger optical and quantum control systems. It is commonly used to drive AOMs directly or as part of feedback loops for laser stabilisation and quantum state manipulation.
