Digilent Digital Discovery

Digilent Digital Discovery is a portable logic analyzer and digital pattern generator instrument. The digital input and output can be connected to a circuit using simple wire probes or breadboard wires. The digital discovery high-speed adapter and impedance-matched probes can be used for the I/O connection of the advanced projects. This USB logic analyzer and pattern generator features a small form factor for easy storage and allows the user to debug, visualize, and simulate digital signals.
