Benefits of the Digital Discover Logic Analyzer, Pattern Generator, and Digital-I/O Instrument
- 24 digital inputs and 16 digital-I/O channels.
- Rates with High Speed Adapter up to 800 MS/s.
- Supported by the WaveForms software application.
Digilent DD Digital Discovery Multifunctional Digital-I/O Instrument
Digilent DD Digital Discovery combines multi-purpose digital-I/O channels, logic analyzer, pattern generator, and programmable power supply in a compact USB module. Makers, hobbyists, engineers and designers can use Digital Discovery to debug, visualize, and simulate digital signals for embedded projects.
- 24 high-speed input pins, 100 MHz bandwidth, 560 kΩ||10 pF. Use as logic analyzer.
- 2 Gbit DDR3 acquisition buffer.
- 16 digital-I/Os. Use a smultipurpose I/O and/or pattern generator.
- Output buffer: 32 kSamples/channel.
- Automatic or manual strength and slew settings for outputs.
- User programmable DIN and DIO LVCMOS voltage levels from 1.2 V to 3.3 V (5-V compatible).
- User power supplies, 1.2 V to 3.3 V (100 mA max.).
- Digital inputs and outputs can be connected to a circuit using simple wire probes or breadboard wires; alternatively, the Digital Discovery High Speed Adapter and impedance-matched probes can be used to connect and utilize the inputs and outputs for more advanced projects.
- Used as an alternative to the 2X16 flywire assembly.
- Provides access for up to 24 high speed logic probes and allows increased sample rates for up 800 MS/s:
32-channel digital logic analyzer, 8 channels at 800 MS/s, 16 channels at 400 MS/s, and 32 channels at 200 MS/s.
- USB 2.0 connectivity, USB-powered.
- Supported by the WaveForms software.
