It is intended to be used in conjunction with the SG5010.

The DA4084 is a modified variant of the AA5001 that replaces IM measurement with a SINAD function for radio equipment maintenance and characterization. The THD+N measurement of the regular AA5001 fails to measure signals with more than 10% noise content accurately because the autotuning of the notch filter will fail at these high noise levels. The SINAD function in the DA4084 performs the same measurement as THD+N but uses additional circuitry to lock the internal notch filter onto the audio tone at a low noise signal, and then maintains this lock for high noise signals up to 50%, which is sufficient for normal SINAD testing to find radio receivers' sensitivity levels.

The DA4084 was supplied in a modified TM5003 rack with an unusable left slot and a linear regulating power supply, but also works in generic TM5000 mainframes. The Army designation for this combination (DA4084 and special power supply) is TS-4084/G.
