Digital Discovery High Speed Adapter and Logic Probes
The High Speed Adapter, for the 32-pin connector on the Digital Discovery, is an alternative to the 2x16 flywire assembly. It provides access for up to 24 High Speed Logic Probes and allows increased sample rates for up 800 MS/s on the Digital Discovery. The adapter is not keyed, and both orientations can be used as the twisted wires are not color-coded.
The Digital Discovery comes with a pack of 16 High Speed Logic Probes. Each cable has a GND (black) wire twisted to a DIN_USR (colored) wire. The wires connect to the High Speed Adapter via a 2-pin female header and two 1-pin female connectors to the device under test. A 100 Ω resistor is embedded in the signal wire on the end closest to the device under test. All GND wires should be connected to the ground of the device under test.
