CD-2 Common Digitizer-2 - A second generation Common Digitizer built by Burroughs Corporation for the FAA. Known as the CD-2.
On 6 Apr 1979 the FAA announced the award of a contract for a second generation common digitizers. The first generation Common Digitizer had military designations of FYQ-47 and FYQ-49. The new CD-2 common digitizer differed because it was microprocessor driven and was dual channeled to permit the equipment to keep working if one channel failed or was shut down.
The FAA contract provided for 106 of the CD-2s to be installed at FAA long range radar sites. Three would be used with airport radars, and seven would be used for training and support services.
In March 1986 the FAA commissioned the first Common Digitizer CD-2, for operational use. The first two CD-2s were delivered to the FAA Academy in Oklahoma City on 11 Feb 1983. The first field delivery took place in May 1984.
