Please note: due to the global semiconductor shortage, we are unable to supply QRF and do not expect availability to improve until mid-2022.
Building on the success of our flagship RF source, MOGLabs is excited to introduce a quad-channel RF synthesizer that offers the flexibility of computer-controlled DDS generation at an economical per-channel price. A robust and versatile digital RF source at a price point that can compete with home-built analogue solutions.
The QRF offers a range of functionality for common AOM tasks such as adjustable frequency shifting, analog AM/FM/PM/PID, intensity stabilisation, and pulse generation. Optional integrated power amplifiers (QRF241) enable most AOMs to be driven directly without the need for external amplification.
The channels are inherently phase synchronous, simplifying phase mod-demod experiments such as IQ-measurement. Each channel has a separate modulation input which can be configured independently. Hardware TTL switching permits rapid pulse generation with extremely low jitter.
An integrated display interface simplifies operating the device, and it can be fully computer-controlled over Ethernet or USB using a human-readable control language. A full software suite is provided, including examples in Python, MATLAB and LabVIEW.

Features
Precise, wide-band frequency control
The QRF is capable of generating output frequencies up to 250MHz at 0.12Hz steps, giving reliable and precise tuning of your output frequency.
An intrinsic limitation of simple DDS systems is that the gain at higher frequencies is reduced. This plot shows typical output power across the output range to help decide whether this product is right for your application. The ARF has a flatter response curve and higher power across the range.
Fast TTL control and pulse generation
The QRF features a high-speed RF switch that enables the generation of rapid RF pulses (blue) using a TTL control signal (red) - with only 40ns latency from input to output!
