Logic analyzer:
- 24 high-speed input channels accessible through one 2x16 connector
- 800MSps input sample rate with maximum 8 inputs with the high-speed adapter
- 400MSps with maximum 16 inputs with the high-speed adapter
- 200MSps and lower with a maximum of 32 inputs
- 100MHz signal input bandwidth
- 2Gb DDR3 acquisition buffer for logic analyzer
- Multiple trigger options including pin change and bus pattern

Multi-purpose digital I/O:
- 16 digital I/Os arranged in two Pmod-style (2×6) connectors
- Each of the 16 pins can be configured for input (logic analyzer) or set as output
- Algorithmic pattern generator
- ROM logic for implementing user-defined Boolean functions and State Machines
- Bus protocol controllers like SPI, UART, and I²C
- 100MSps (max) output sample rate
- Automatic or manual strength and slew settings for output
