While viewing the spectrum analyzer screen, a pure noise signal as shown in Figure 1
will probably be observed. Additionally, some transponder signals may be observed
above the noise signal as shown in Figure 2.
The following steps provide the procedure for acquiring a satellite.
Step 1
Manually move the antenna in the azimuth (scanning back-and-forth) to achieve the
maximum (greatest amplitude) transponder signals.
•
Scan in one direction until the amplitude continues to diminish and then scan in the
opposite direction until the same condition occurs.
•
Return to the position yielding the greatest amplitude.
