Functional Description
The digital to analog converter (dac), also called the analog receiver digital instrumentation (ardi) box andthe receiver instrumentation box (rib), is organizational aerospace ground equipment used with an oscilloscope to detect and isolate faults in the analog receiver of the e-3 (awacs) radar sets an/apy-1 & -2 including the radar system improvement program (rsip). The dac provides self-test capability which distinguishes between a fault in the dac and the unit under test
