Description
Available NOW!
The MOGLabs XRF RF synthesizer is an agile RF source with the unique capability of fast (10MHz) analogue modulation of frequency, amplitude and phase. It is priced to stop you building your own, bullet-proof so you don't have to be frightened of turning it on, and incredibly agile to meet the needs of quantum ion and BEC research. And it has MOGLabs ergonomics, so you can use it as a simple self-contained AOM driver, or as an optical noise eater with analogue input and built-in PID feedback.
The device provides two channels of agile RF frequency synthesis with high-power RF amplifiers included. Each channel spans a frequency range of 20 – 400MHz with output power up to 4 watts (+36dBm), extended down to 15kHz at low power (0.25mW, -6dBm). The two channels can be used as simple manually controllable AOM drivers via front panel knobs to adjust frequency and output power, with simultaneous FM and AM (or PM) modulation with 10MHz bandwidth (fully anti-aliased), and servo feedback built-in for laser noise-eating or frequency locking.
The computer interface (10/100 ethernet and USB) allows full control of all parameters, including loading of FM, AM and PM tables for triggered or looped playback. Fast frequency chirps or complex waveforms can be defined with 0.23Hz, 0.2mW and 0.4mrad (0.02°) resolution in time intervals as short as 16ns. 16 digital input/output signals can be individually controlled in synchronisation with the DDS sequences.
The XRF uses a fast FPGA to drive two AD9910 DDS cores. Communications are handled by two separate microcontrollers. FM, AM and PM sequences can be incredibly complex using interpolation, repeats, loops, ramps, and external triggers.
