6.1.14 Ku-Band version only: Cable calibration
If you have the Ku-Band version of the VSAT system, use the web interface to make a cable
calibration to ensure that Tx power is calibrated at all frequencies.
1. Deploy the antenna.
2. On the page SERVICE > Calibration click Start in the section Cable calibration.
3. Wait typically for 2 minutes for the calibration to finish.
A message is displayed when the calibration has been completed successfully.This screen
shows how much attenuation margin is left for the antenna cable. This indicates whether
the antenna cable and connectors are in good condition and well crimped.
When servicing the system it is recommended to make a cable calibration to check if the
antenna cable is still in good order. If the attenuator margin changes by 2 dB or more after
a cable calibration, it is recommended to do a P1dB compression measurement with the
satellite operator to verify that the VSAT modem configuration is correct.
The VSAT system is calibrated now. If the calibration failed there will be a message on the
calibration screen.
6.1.15 To line up or jog the antenna
You can use the Lineup/Jog function to deliberately offset the antenna position. This is
useful when you define blocking zones, for testing and troubleshooting and sometimes also
during commissioning.
1. Connect a PC to the LAN1 or front LAN connector at the ACU.
You may also use WLAN, if it is configured.
2. Open an Internet browser and type the default IP address: http://192.168.0.1.
3. If the antenna is not already deployed, click Deploy in the top bar of the web interface.
4. Navigate to the page SERVICE > Jog and click Activate Jog or Activate Lineup.
• Lineup is typically used during commissioning. If you selected Lineup, the antenna
will be able to transmit during the Lineup procedure. You can enter offsets for the
For the system to work properly you must make a cable calibration in the
following cases:
• After installation
• After replacing antenna cables
• After replacing the BUC
•After service
WARNING! Stay clear of the antenna during Cable calibration! The antenna
is moving and transmitting during the calibration procedure. For Stay clear
area see Mechanical “stay-clear” area, EXPLORER 8100 on page vi or
