Abstract
The Mark III Data System Development Plan is encouraging engineers designing equipment for use in the Deep Space Network to utilize computer control and monitoring. It is becoming apparent that the difficulty of development and cost of software are prohibitive. A concept called firmware is proposed. Firmware is a design concept which directs the engineer to employ special-purpose digital and/or analog circuitry whenever possible to reduce software or interface requirements. The Ranging Demodulator Assembly (RDA) is being developed under the firmware concept. By employing firmware, the RDA interface and software requirements have been kept to a minimum. The phase calibration of the RDA is achieved with a single switch or one-line command from the computer. Monitoring is handled by the firmware which supplies one line to the computer indicating the operability of the RDA.
