MIL-PRF-49166/1B(CR)

3.5.1.4 Scan angle. The scan angle shall be adjusted to 13.0, �0.3 degrees.

3.5.2 Interlace. The MX-9872(V)1/UA shall operate in the 2:1 interlace mode. The

interlace switching time shown in Figure 1 of MIL-PRF-49166 shall not be greater than 2.5

milliseconds (ms).

3.5.3 Scan direction. The MX-9872(V)1/UA shall show the waveform shapes and phase

relationships in Figure 1 while operating in the 2:1 (side) or the 2:1 (rear) interlace mode.

3.5.4 Power consumption. Power required to operate the MX-9872(V)1/UA shall not

exceed 7.5 watts.

3.5.5 Scan efficiency. The MX-9872(V)1/UA scan efficiency shall be a minimum of 70

percent.

3.5.6 Scan jitter in azimuth. Jitter time shall be 12.5 microseconds maximum.

3.6 Workmanship. All parts, components, assemblies or sub-assemblies shall be free of

smudges, excess solder, metal chips or the existence of any foreign material on any surface.

Bearing assemblies shall be free from rust, dirt or tool marks. Wires and integrated circuitry shall

be protected from contact with rough or irregular surfaces and be shielded from shorting.

MIL-HDBK-454 may be used as guidance.

3.7 Environmental conditions. See MIL-PRF-49166.
