Transmitter RF Power Level.
Ensure the transmitter power level is set as required. The power level is selectable in 3dB
steps (0.25W, 0.5W, 1W, and 2W for a 2 Watt system, and 1.25W, 2.5W, 5W, and 10W
for a 10 Watt system).
Note: EX7100 RF power output is measured as PEP (Peak Envelope Power
1
.
The EX7100 exhibits a reduced power output level during the initial period while
attempting to establish a link with the remote terminal, to minimise local coupling
into the receiver. The power level will ‘ramp’ upwards until reaching the selected
level after successful modem lock.
1) From idle, press ‘Enter’.
Use the arrow keys to enter the First Level
password ‘1111’ and then press ‘Enter’.
2) Use the up and down arrows until the →

→ is
next to RF Parameters and then press
‘Enter’.
3) Use the up and down arrows until the →
→→
→ is
next to Tx Power and then press ‘Enter’.
4) The current Tx Power will be displayed.
Press the down key followed by ‘Enter’ to
change the power level.
5) You will be asked for the Second Level
password. Exicom’s factory default is
‘1234’. If the default password does not
give access, see your System Engineer as
the password may have been changed
(refer to Section 3.4.1 for details).
6) Use the up and down arrow keys to select
the required Tx Power Level and then
press ‘Enter’.
Note that the currently selected setting is
indicated by an asterisk.
7) The new setting is now in effect.
Press ‘Escape’ until the display returns to
idle.

Average power, as measured with a Bird Wattmeter, is calculated as 7.25 dB lower than PEP, as described in the ITU
Radio Relay Handbook, 1996, pages 152-153. (EX7100 roll-off filter is 0.3)
