The results are displayed graphically and are stored in the IDU flash memory for further consultation.
Frequency scan is to be performed separately on each terminal. The user defines maximum and
minimum frequencies to scan. The local transmitter is muted, while the system measure Receive
Signal Levels frequency per frequency.
Note : To proceed to a frequency scan, it is necessary firs to change the current capacity and
modulation to a 2 E1/QPSK mode.
When clicking on the frequency scan menu this windows appears :
Define the scan frequency range by moving the cursors, start by clicking on the Proceed button. The
