Sat Operation
SCAN
With the function SCAN, satellites can be searched for, whose transponder fre- quencies are not known. Here, the frequency range of 920 to 2150 is continuously scanned for the receiving signals. If the receiving signals are available, the recep- tion level is displayed on the screen as a bar diagram. Four measurement ranges with the dynamic of each 40 dB are available for the bargraph display. The meas- urement range is automatically preselected.
Bargraph | Level range | Comment |
display |
|
|
I | Automatic range change at 70 dBµV | |
II | Auto. range change at 50 and 90 dBµV | |
III | Auto. range change at 70 and 110 dBµV | |
IV | Automatic range change at 90 dBµV |
The level can be controlled with an acoustic signal. The frequency of the acoustic signal varies in proportion with the receiving signal level. The volume of the acous- tic signal can be changed.
The screen shows the bargraph display, which changes in proportion with the input signal.
The field SCAN lights up yellow, as soon as the softkey is pressed. The entire Sat frequency range is now scanned. By pressing the button once more, the process is stopped and the softkey display changes to “scan off.“
