and verify that the voltages (Vol_9 and Vol_50) and current (Cur1_50, Cur2_50)

are showing real values and not all 0s.

6. You are now ready to bring the TX up to power. To accomplish this, slowly

increase the drive level out of the Exciter by increasing the POWER setting in

the Exciter RF submenu while watching the PA_Fwd power increase

accordingly on the PAC submenu (you will need to navigate between the Exciter

RF and PAC submenus).

Begin to slowly raise the FWD System power by using the UP button on

the Exciter, while monitoring the PA_Fwd system power meter on the

Controller HOME screen as shown below.

7. Continue to slowly raise the FWD power until you reach the full 280W, or your

desired TPO. Be careful to make small increases in the value of POWER as you

approach the desired output level.

8. Check the SNR and Shoulder (LIMD and UIMD) RF performance of your

system on the Exciter hi level status screen as shown below. Linear and Non-

Linear corrections were already performed and optimized at a TPO of 280W in

the factory and so the stored correction coefficients should produce good results.

If you are operating at a TPO less than 280W and wish to rerun corrections,

please proceed with the following steps, otherwise please skip ahead to step 12.
