We discussed custom instrumentation for high-speed single photon metrology. We focus on the difficulty of GHz data sampling and provide some techniques on how to accomplish it. We also discuss the benefits of field programmable gate arrays as the basis for programmable instrumentation because they have superior performance when processing this high-speed data in a pipeline manner compared to computers. We provide a few examples of research instruments developed at NIST that use these concepts. We also provide some associated reading references for high-speed circuit design and signal interfacing as well as high-speed printed circuit board design considerations.
