内容: This option allows visually evaluate the signal quality of the incoming satellite signals. The clear and generous display of all measured values offers the on-site technician a valuable decision support in installing and troubleshooting. A real satellite signal is always coming along with disturbances. The worse the signal quality, the greater the distribution in the decision field, the signal clouds increase. This means on the other hand, the better a signal is the smaller the signal clouds are indicated. If the signal is so severely disturbed that some signal conditions exceeding the decision limit, bit errors are the result, often with the familiar picture and sound effects. The color gradation provides information on the frequency distribution of the signal states. The grading is done in blue, green, yellow and red with increasing number of hits.
