 The basic functions of Pixelator are implemented on the [NI PCI6602](https://www.ni.com/docs/en-US/bundle/ni-660x-specs/resource/372141b.pdf) Counter/Timer card. (In future, other options will be implemented that avoid NI cards altogether.)
 
-The NI PCI6602 card provides the clock that governs the measurement dwell time and triggers detectors, often referred to as the "pixel clock". These are constructed from the first 3 subdevices (of 8 total) using the following external connections.
