Questions regarding design choices of CW313 board

Hi,

I recently received a Husky and the much more compact CW313 board for targets, which is nice.

But I had a few questions regarding some design choices about it:

  • The Husky and the CW313 are supposed to be designed to work together and I was expecting the SMAs to be respectively connected to SHUNTL and SHUNTH signal to leverage the diff input that the Husky has. But both SMAs are equivalent and wired to SHUNTL.
  • We can provide our own power rails using either the test probes or a 0.1" header, which is amazing but I think you forgot to add the GND signal to the header :slight_smile:
  • Regarding the PCB to convert CW308T targets, I’m a bit surprised that the “top” of the target is facing the CW313 edge connector because quite a few targets, e.g. MCP ones, have a big DB9 connector there, that will get on the way.

Otherwise, thanks a lot for Husky + CW312! That’s such a nice improvement overall. More compact and easier targets to design, better ADC, etc.
Overflow detection allows to programmatically find the best gain to avoid clipping.
