Pico has released a new two channel scope.   This new scope offers a perfect balance of cost, ADC speed, and sample buffer, in a 12 bit two channel USB 2.0 interface platform.  The performance is outstanding.  The two channels share a 20mhz ADC and a huge 512,000 point sample buffer.  Plug those specs into the Autonerdz Sample Rate Calculator  

This is the same as the new four channel scope but with only two channels and costs much less.

We still support the parallel 212 series units but have discontinued them.
