The operator control center will instruct you to adjust your power in positive or negative steps. Never
make power adjustment steps larger than 5 dB. Please update the transmitted power level using the above
dvb tx cw on command until the desired power level is measured at the control center.
When the operator confirms that the correct power level has been reached, turn off the CW transmission
with dvb tx cw off before storing this power level as the nominal IDU output power level to be used
for transmission. Type the CLI command:
dvb tx outpow <pow>
where “pow” is the TX IDU Output Power level in dBm.
Verify the setting by issuing the follwing CLI command:
dvb tx show
Save the setting by issuing the following CLI command:
save config
In the following example, a complete power correction routine is carried out.
Example:
dvb tx cw on -30 14100000
The operator instructs you to increase power by 5 dB (i.e. pow = -30 + 5 = -25). Type:
dvb tx cw on -25
The operator instructs you to decrease power by 3 dB. (i.e. pow = -25 - 3 = -28). Type:
dvb tx cw on -28
The operator instructs you to increase power by 1 dB. (i.e. pow = -28 + 1 = -27). Type:
dvb tx cw on -27
The operator confirms that the correct power setting is obtained. Confirm the nominal power setting by
storing this power level. To configure the nominal power level, turn off the CW transmission with:
dvb tx cw off
Then type the CLI command:
dvb tx outpow –27
Verify the setting by issuing the following CLI command:
dvb tx show
Save the setting by issuing the following CLI command:
save config
