10. The TAVD-500 LCDs show the user the present status of the amplifiers. Adjust RF output
power to desired level (see Important RF Power Notice in previous section). Verify that the FWD
Power reads 400 to 500 Watts on the PA enclosure. The output power level can be adjusted
using the modulator or processor’s RF output level adjust. Keep in mind that the system will
shut down should the forward RF output power level be exceeded.
11. Ideally, the RFL Power should read zero. However, should a high VSWR be detected, the
system will automatically shut down and cycle as previously described.
12. Verify that the power supply reads approximately 30 Volts DC (see supplied final inspection
sheet for factory settings of power supply levels) on the LCD of the power amplifier.
13. Look at the transmitted output using a suitable monitor. The picture and sound quality should be
clean and sharp. If the output picture and sound quality is unsatisfactory, check the input
signals, connections to the antenna system, antenna and transmission line VSWR, and the
physical condition of the antenna.
If reception problems are encountered, and the quality of transmission is satisfactory, the difficulty is
often with the receiving antenna or with obstructions in the path between the transmitter/translator
and receiver.
