http://www.bitscope.com/ PIC based Mixed Signal Capture Engine called Bitscope. Captures analog and 8 digital channels at 25 Mhz (3kHz min) in a 16K deep buffer so you get an oscilloscope and logic analyzer in one package. Uses a host computer for control and display through a 56K RS232 serial port. A nice piece of engineering and the design is "open" so you can build as much or as little as you want. Board, main chips or fully built and tested unit in a case ($400) available.

Signal Generators
Analog Devices AD9850 DDS has been used to design (Documentation, schematics, sources available at http://www.geocities.com/CapeCanaveral/Lab/9595/) a generator with the following features:
Uses two 16F84 microcontrollers, one for a 4x4 keyboard, the other for LCD, encoder, DDS, shift-register as DAC
Range 0.1 - 40MHz
Steps selectable from 1, 10, 100Hz, 1, 10kHz
Step multiplier selectable from 1-9
Frequency entry through keyboard in 1Hz precision
Keyboard commands to sweep frequency up or down
Keyboard command to "wobble" frequency in 250 steps, with corresponding DAC voltage for oscilloscope X-input which is particularly useful for making measurements on filters.
Output level from 0 - +10dBm, level is held constant within 1dB over range.
"Digital Frequency Synthesis" by Tom Napier in issue 99 (October 1998) of Circuit Cellar INK. Uses a PIC as a Digital Frequency Synthesizer. Richard Ottosen has developed an improved version for the Ubicom SX sxncoex.zip
