Quite doable. Example where 12 bit SAR is used, there is enough BW and speed multi
channel can be done. If 16 bit needed the onboard DelSig will do 48KSPS at 16 bits.
The A/D drives DMA request to handle the transfer to RAM, the counter and ISR handle the
2000 sample frame management.
Single chip (including precision Vref), used small fraction of its resources. If needed signal
path filtering there is onboard digital filter for that purpose. emfile component (in PSOC land
a component is an onchip resource) shown to handle SDCARD and USBUART to interface to
PC if needed, as well as graphic LCD internal component if needed.
Other onchip resources (including ARM core) -
IDE (PSOC Creator) and compiler free, board for this probably the $ 15 board.
Here is example of an oscilloscope/logic analyzer/function gen done with it. Dont
know why they used a crappy puke lime green display with it. Could have been TFT
or OLED......
Commercially available lab equipment like oscilloscopes, logic analyzers, and function generators are bulky and expensive, making them difficult to use

Hi everyone, I found these articles http://www.embedded.com/design/prototyping-and-development/4421857/Configuring-a-PSoC-for-a-DIY-oscilliscope-logic-analyzer---Part-1...
