scope:

The detail requirements of this specification sheet together with the general requirements of MIL-C-50652 comprise the complete requirements for the Range Control Fine Delay Decoder (RCFD Decoder) used in the Range Computer CP-888/VPS-2, part of Radar Set AN/VPS-2. The RFCD Decoder forms part of a binary to decimal decoder for 1.25 meter range increments, provides a single output called the E/L coarse output from the RCFD high and low data, and has circuits for detecting minimum and maximum range rates and velocity of less than 10 meters per second.
