The ES10 has a built in RF power meter function, which monitors the total level at the
input of the transmitter as given in the right most column of the table beyond. This
level depends on the number of unmodulated and modulated AM-TV, FM-radio and
QAM channels.
The input monitor controls the INPUT LED. As long as the input level is within the AGC
range of the transmitter to obtain the specified total rms modulation index, the input
LED is lightening in green colour.
If the number of channels to be transmitted is differing from the specified number of
channels the total input power level can be calculated using the following expression:
P
intot
/dBm = 10 log (n) + U
in
/dBµV –108.7
where
• P
intot
is the total rms input power level
• n is the number of channels
• U
in
is the input voltage per channel (nominal 80 dBµV) for unmodulated carriers.
If the input level voltage of all channels is 80 dBµV the diagram below can be used to
determine the total input power level.
