MGC SETTINGS
In MGC mode, the user has the ability to control the level over a range of 60 dB. The default setting is
0000. Each count represents approximately 0.5 dB worth of attenuation. For example, the command
string “ATTA0044” sets Attenuator 1 to approximately 22 dB of attenuation. Table 11 illustrates the
MGC attenuator settings.

When changes are made to the system settings, they are only valid as long as the unit remains powered
on. To keep desired settings, the CONSTO command will store the current settings to memory, and the
stored settings will be retained and used on the next startup. Note that any settings saved using
CONSTO will overwrite the factory settings.
