Signal Ranger MK3

Signal Ranger MK3

SignalRanger_mk3 is a fixed point DSP board featuring a TMS320C6424 DSP running at 590 MHz, a 6-input/6-output 96 kHz/24-bit analog interface designed for pro-audio and high-performance control applications and a high-speed USB 2 interface, providing fast communications to the board. The USB Windows driver allows the connection of any number of boards to a PC.

The DSP board may be used while connected to a PC, providing a means of exchanging data and control between the PC and DSP in real-time. It may also be used in stand-alone mode, executing embedded DSP code. The ADCs and DACs have a mode of operation (default) where the bandwidth goes down to DC. This allows the board to be used in high-performance control applications. Given its high-quality analog IOs, its programmability and the fact that it can work as a stand-alone board, the SignalRanger_mk3 board may be used in many applications.
