13. The TAV-1000 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 800 to 1,000
Watts on the combiner/filter enclosure - depending on signal content. The system is set up for 1,000 watts
peak visual power using the sync and blanking signal and should read 1,000 watts FWD Power on the LCD
under this condition only. 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.
14. 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. This is also a peak wattage reading.
15. 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 and power supply enclosures and
24Vdc on the combiner/filter enclosure.
16. 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.
