1-8. Description.

The digital processor test set is a portable unit requiring no special installation facilities. The unit contains power

supplies and distribution networks requiring 3-φ, 115-V ac, 400-Hz line voltage input. +28 V dc is required when testing

the df display or communication processor control-indicator. Twelve solid state circuit card assemblies (CCAs); one

blower; and front-panel controls, indicators, and connectors comprise the primary assemblies of the digital processor test

set. See table 1-1 for digital processor test set power and signal connections. In addition, two extender CCAs are

included to facilitate troubleshooting of the digital processor test set and the equipment units under test.
