We are looking for options for detecting RF pulses up to 20 GHz, and found that CN0366 circuit configuration could be a candidate to fit our needs. I noticed that it requires the EVAL-SDP-CB1Z interface board for USB communication and that that board only has compatibility with Windows. Is there a way to make this circuit work when using a Linux RT controller either by using direct SPI lines or using USB communication compatible with such a system? If so, where can I find documentation relating to SPI commands or more information on what protocol I could use. If there were ways to communicate with a PXIe NI chassis over SPI then this would be a good fit for our application.
