5.11 Verification of distribution networks
(SAT IF Test / Attenuation Test)
This application allows to verify easily the TCI features (Telecommunications
Common Infrastructures) before the antennas and head-end devices are operative. The
procedure allows to evaluate the frequency response of a whole TV signals distribution
network by means of two steps:
NOTE: For this application the use of PROMAX’s RP-050 / RP-080 or RP-250 signal
generators are required, for which they have been specially designed.
1.- CALIBRATION
Connect the generator directly to the PRODIG-5 (EXPLORER) using the BNC-F
adapter.
Power on the RP-050/RP-080 through the EXPLORER, for it is necessary to set
the External supply function (see section '5.7 External Units Power Supply') pressing
key
[11], and the rotary selector [1] for setting a voltage of 13 V.
Finally, select the SAT IF TEST application on UTILITIES
[22] menu for SAT
band, or the ATTENUATION TEST for terrestrial band, connect the generator to the
point where antenna will be connected (signal source) and by means of the horizontal
cursors
[6] select the Calibrate function (see following figure). Wait for some
seconds until the calibration process of three pilots is completed.
