PROGRAMMING

Preset Transmit Mode

Preset transmit mode allows the user a convenient means of automatically

setting bandwidth, FEC, modulation and video frame rate/compression

based on link distance requirements. Options are: None (preset mode not

used), Short Range, Medium Range, Long Range, Ultra Long Range.

Output Power

Output power selects one of two output power attenuator settings; low

power or high power, typically the low power setting is the larger of the two

attenuator settings and is used, for instance, if a power amplifier is added

to the transmitter and the output power needs to be lowered substantially

to prevent overloading the input of the power amplifier.

Output Attenuation (dB)

Output attenuation (dB) is the high power attenuator setting.

This control can be used to make minor adjustments to the output power

level, but in normal operation should NOT be changed from factory

settings. (0 attenuation = full output power, greater than 0 attenuation =

reduced power in 0.25 dB steps.)

Output Attenuation low (dB)

Output attenuation low (dB) is the low power attenuator setting.
