7. Check the SNR and Shoulder (LIMD and UIMD) RF performance on the
front panel screen of the exciter or by pressing the Exciter Icon on the
Controller HOME screen. (Change the value of CFR or rerun correction
if necessary to obtain optimal performance).
8. With your TX operating at your desired output power and with good RF
performance, the next step is to set up and re-engage the TX AGC. To
accomplish this, slowly increase the value of POWER in the Exciter RF
submenu to raise the output power of the system to 1.1 x desired TPO (for
example 1650W if a 1500W TPO level is desired). (Note: You are bringing
up the TX to 1.1 x desired TPO to provide 10% headroom for AGC
operation).
9. Navigate to the AGC screen on the Controller (by pressing the CONFIG
button and then the AGC button). Be sure the AGC Target FWD power is
set to 1500W, or whatever TPO level is desired for operation, and then
press the unlit AGC button to engage the TX AGC and turn this button
Green.
