Figure 94: Tracking Error Meter
As the antenna slews towards the radiating target, the Meatball moves toward the center (cross hair) position of the
Error dial, in both X and Y axes, (provided that the meter is calibrated correctly). As the antenna slews away from
the target, the Meatball moves away from the central crosshair position on the error meter. If the tracking antenna is
slewed in Azimuth CW and CCW (only) across the radiating target, the Meatball should move along the X axis of
the error meter, with little to no deflection in the Elevation up and down (Elevation) deflection.
The Tracking error meter provides the operator with digital readouts of the Azimuth and Elevation track errors, in
numeric format, located in the two small displays fixed to the bottom of the meter, as shown in Figure 94. When the
system is auto tracking a radiating target, in both Azimuth and Elevation (both TRACK buttons are green) the
Meatball should be centered at or near the central cross hairs location within the Tracking error meter. This indicates
the antenna is pointed at the radiating target and is well within the antenna
’
s beamwidth.
The user has the option of enabling and disabling two additional lines on the meter. The lines are 45° from the X and
Y planes. These aid in where AZ and EL errors are approximately equal, and display green when feed is On and
modulated, and red when feed is Off with no modulation signals present, as shown in Figure 95.
