ADJUSTMENT OF LEVELS

9.1 Verifying the TO modules
Check that the input COFDM channel hook-up IN indicator (21), the 'correct
MPEG transmodulation' indicator (26) and the 'correct HF output channel '
OUT indicator (27) on the transmodulators are activated.
9.2 Levels of the TO modules
Connect a field measurer to the TEST connector of the PA amplifier, and
verify that the output of said amplifier is charged using a distribution cable
or with a 75 Ω charge, of the RS-275 (cod. 9120011) type. Tune the output
channel measurer of the TO module furthest from the amplifier and verify
that the output level of the TO module is at -0 dB. Tune each of the
remaining TO and adjust the output level of each TO module until reaching
the same level as that in the TO module, which is furthest from the amplifier.
