Verification of distribution networks (SAT IF Test)
This application allows to verify easily the TCI features (Telecommunications
Common Infrastructures) before the antennas and the head-end devices are operative.
The procedure allows to evaluate the frequency response of a whole FI distribution
network by means of two steps:
NOTE:
For this application the use of PROMAX's RP-050 FI simulator is
suggested, for which it has been specially designed.
1.- CALIBRATION
Connect the RP-050 directly to the PROLINK-4C using the BNC-F adapter.
Power on the RP-050 through the PROLINK-4C, it is necessary to set the
External supply function (see section '4.8 External Units Power Supply') pressing key
[27], and the rotary selector [4] for setting a voltage of 13 V.
Finally, select the SAT IF TEST application on FUNCTIONS menu from TV
mode and SAT band, when it appears the screen from figure 34, press the rotary
selector [4] to accede to the FUNCTIONS menu and using the rotary selector [4] to
accede to the Calibrate function (figure 35). Wait for some seconds until the calibration
process is completed shown by a white square crossing through the three pilot
frequencies.
