The Azimuth and Elevation axis position display meter breakdown:
•
AZ Axis Velocity readout
•
Actual antenna pointing position
–
Orange Pointer, in this case (359.994°)
•
Commanded antenna pointing position
–
Blue pointer (under orange pointer)
•
The central, digital, numerical readout for the Commanded and Actual antenna pointing position (both
indicating 359.994°)
•
CCW and CW limit indicator location
–
Not present is a slip ring system (no AZ limits). The EL position
feedback dial always displays the Up and Down hard (electrical) and soft limits.
•
Slave position digital readout
–
Green numerals indicate slave angle(s) are present. Red blanks (- -.- -)
indicate NO slave angles are present.
•
Analog dial divisions graduated to every 5 degrees (0 to 355.500 degrees)
The Elevation Status Display includes four LEDs for limits. The user configurable software limits are indicated by
yellow LEDs and the electromechanical limits by red LEDs that illuminate when reached. The range of the user
configurable limits are indicated by the red tick marks on the degrees indicator, as shown in Figure 92. After the
software limits are set, the non-reachable degrees tick marks are blocked in red.
When the user configurable Multi-Path Clipping (MPC) is enabled, the antenna will not go below lines on the
degree indicator marked in yellow. In Figure 92, the MPC is set for 0.0°. During a target track, the EL axis will not
track below 0° when MPC is enabled.
Note:
MPC only applies to the Elevation “
d
own” direction

Tracking Error Meter
The Tracking (Error Meter) is located between the EL and AZ Axis status windows. It provides a visual
representation of the radiating targets location within the tracking antenna’s beamwidth.
The green indicator, shown in the middle of the meter, represents the radiating target relative to the antenna RF field
of view. This indicator is commonly re
ferred to as the “Meatball
.
”
The crosshairs represent the Cartesian Coordinate System. This divides the antenna tracking view into four
quadrants, as shown in Figure 93. When the green dot/Meatball, is at center or origin of the planes, the target is
being tracked at optimum.
