•
Forward Couplers: 48.8dB @ 88MHz to 47dB @ 108MHz
•
Reflected Couplers:43.8dB @ 88MHz to 42dB @ 108MHz
(Typical tolerance is +/- 0.1dB at 108MHz, but is not guaranteed)
For frequencies between 88 and 108MHz the actual coupling ratio can be extrapolated
linearly. For example: At 98 MHz the typical Forward Coupling ratio is 47.9dB.
5.9 Maximum Power Settings
There is a maximum power limit which can be set for each of the transmitter power
settings, LOW and HIGH. The “MAX HIGH SET” sets the maximum power output
when the transmitter is on HIGH power. The “MAX LOW SET” sets the maximum
power output when the transmitter is on LOW power. See Table 5-2 on page 5-36 for
default settings.
The MAX HIGH Power limit is set as follows:
STEP 1
Turn the transmitter on at HIGH power and set the power output to a
power level which is less than the desired maximum power using the
Raise and Lower buttons.
STEP 2
To enter a new MAX HIGH setting go to the MAX HIGH SET screen,
[HOME, MORE, CONFIGURATION, B, C] Then choose the desired
modulation format to change to the new maximum power level and
press [BACK] to save the changes.
STEP 3
Press Raise to make sure the power level will not go above the new
MAX HIGH setting. The MAX HIGH setting in Step 2 can be adjusted
slightly to get the exact desired power level.
STEP 4
Repeat steps above for all desired modulation formats.
The MAX LOW Power limit is set as follows:
STEP 1
Turn the transmitter on at LOW power and set the power output to a
power level which is less than the desired maximum power using the
Raise and Lower buttons.
STEP 2
To enter a new MAX LOW setting go to the MAX LOW SET screen,
[HOME, MORE, CONFIGURATION, B, D], then choose the desired
modulation format to change to the new maximum LOW power level
and press [BACK] to save the changes.
