FreeSRP

The FreeSRP comes in a small, portable form factor (7 cm x 11 cm) that can be completely powered from USB. Its frequency range is 70 MHz to 6 GHz, it has a sample rate of up to 61.44 MSps, an onboard FPGA, and streams acquired signals to a computer in real-time over USB 3.0 -- aiming to balance a useful and powerful set of specifications with an affordable price and a compact form factor ideal for field use.
