www.digilentinc.com  -> Digital  Discovery $199.99


The Digilent Digital Discovery=E2=84=A2 is a combined logic analyzer and pa=
ttern
generator instrument that was created to be the ultimate embedded
development companion. Digital Discovery was designed to optimize channels,
speed, and portability. A small form factor facilitates easy storage and
provides a whole suite of advanced features to allow you to debug,
visualize, and simulate digital signals for most embedded projects. 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. The Digital Discovery is
driven by the free WaveForms software and can be configured to be any of
the below instruments:

   - 32-channel digital logic analyzer (1.2=E2=80=A63.3V CMOS, 8 channels a=
t
   800MS/s*, 16 channels at 400MS/s*, and 32 channels at 200MS/s)
   - 16-channel pattern generator (1.2=E2=80=A63.3V CMOS, 100MS/s)
   - 16-channel virtual digital I/O including buttons, switches, and LEDs =
=E2=80=93
   perfect for logic training applications
   - Two input/output digital trigger signals for linking multiple
   instruments (1.2=E2=80=A63.3V CMOS)
   - A programmable power supply of 1.2=E2=80=A63.3V/100mA. The same voltag=
e
   supplies the Logic Analyzer input buffers and the Pattern Generator
   input/output buffers, for keeping the logic level compatibility with the
   circuit under test.
   - Digital Bus Analyzers (SPI, I=C2=B2C, UART, Parallel)

**Note: to obtain speeds of 200MS/s and higher, the High Speed Adapter
<http://store.digilentinc.com/digital-discovery-high-speed-adapter/> must
be used. *

The Digital Discovery is designed for anyone embarking on embedded
development; with features and specifications deliberately chosen to
maintain a small and portable form factor, withstand use in a variety of
environments, and keep costs down while balancing the requirements of
operating on USB Power.



Just got one and it is nice.
