14. Apply a video signal (1 volt P-P) to the video input terminal.
15. Slowly increase the output level adjustment while watching the RF Output level on the ADP500.
When the output gets up to 50% indicated power stop the adjustments.
16. Using the ADP500 reected power indication check the LOAD reected power. This should be
less that 5% reected.
17. Return to the PA current readings on the ADP500 to verify that all the currents are approximately
the same.
18. With successful performance thru step 17, the transmitter output power can be increased using the
output level adjustment on the modulator to achieve 100%. The aural power can be added at this time
not exceeding 10% of output p-sync power as indicated on the ADP500.
