Uncoupled Operation

During uncoupled operation, the ALC and attenuation values are

changed independently.

In some applications, it is advantageous to control the ALC level and

step attenuator separately, using combinations of settings that are not

available in coupled operation. Uncoupled operation is accomplished as

follows:

• by adjusting the ALC value from the main Soft Front Panel, only the

ALC level is changed

• by adjusting the attenuation value from the main Soft Front Panel,

only the attenuation is changed

NOTE Uncoupled operation is always recommended when in external leveling

mode and must be used when specifying points in a list.
