Interesting DAQ Deals

I think the data acquisition (DAQ) market could use some new players.  For example, affordable but low jitter USB D/A converters do not exist, and Ethernet DAQ systems seem stuck in the stratosphere.

However, I recently come across a couple interesting products that are quirky, but would make a great fit for the right application:

  • The Dataq DI-145 is, at $29,  probably the cheapest USB A/D converter available.  It has a lot of limitations (such as maximum 240Hz sample rate, fixed +/- 10V input range, and 10-bit resolution), but the price is hard to beat.
  • The Data DI-149 adds substantially more capabilities (such as 10KHz maximum sample rate) for a mere $59.
  • The Digilent Analog Discovery Lab is the most affordable high speed DAQ system I’ve ever seen, with dual 14-bit 125MSPS A/D and D/A converters.  Regular price is $199.  The documentation is pretty sparse; apparently right now it can only be used with their free WaveForms software, but supposedly they are working on an API so you can use it with your own program.
