SRL QuickSilver QS1R VERB
- The QS1R VERB is the most advanced open source digital down conversion (DDC) receiver board on the market. It features a Linear Technologies LTC2208 16 bit, 130 MSPS Analog Digital Converter (ADC) and an Altera EP3C16 Cyclone III FPGA. Connectivity to the PC is through a high speed USB 2.0 interface. QS1R covers 15 kHz through 55 MHz in its standard configuration and can be used in undersampling applications to 300+ MHz.
