12.3 RUNNING CORRECTIONS
Local Control:
This section guides you through the process of running Linear and Nonliner
Precorrection (You may also reference the Exciter User Manual for additional
details and instructions on running corrections). If you are operating at reduced
power you may wish to rerun corrections to achieve better RF performance.
Normal operation for the 1.5KW TX is to run with the Transmitter AGC enabled
to compensate for slight variations in output power due to changes in
temperature, AC mains, etc. It is not recommended to run corrections with AGC
enabled, as the correction process can at times produce slight changes in output
power.
1. Please navigate to the Controller AGC screen (by pressing the CONFIG
button and then AGC button) and disable AGC by pressing the Green
button (as shown below), so that the button then becomes transparent
(blue). This indicates that AGC is OFF.
2. Adjust the Exciter POWER setting under the RF submenu to achieve the
desired Forward System Power (1500W for example) as monitored on the
Controller Home screen.
