Abstract
A PDP-11 computer-controlled UNIBUS analog-to-digital (A/D) converter has been designed and constructed for use in the DSN Planetary Radar Data Acquisition System. The converter is intended for synchronous quadrature-pair sampling and can be programmed to automatically transmit the sample values via direct memory access (DMA) to any desired blocks of memory locations. The article describes the converter in detail, and gives information on mechanical construction, data-transfer rates, self-test and calibration provisions, and programming.
