The QRF is ideal for precise, wide-band frequency control. It 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.
For 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.
The channels are inherently phase synchronous, simplifying phase mod-demod experiments such as IQ-measurement. Each channel as a separate modulation input and can be configured independently. Furthermore, 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. Full software suite, including examples in Python, MATLAB and LabVIEW provided.
