Revision 2

A–16

A.4.3

Offset Adjustment

Use the offset to compensate for cable and switch losses. When you initially set

up and test the system, you must force each converter to backup, and adjust the

offset to minimize gain mismatch between the normal and bypassed mode. This

offset will be different for each converter and is stored in a table in the backup

unit.

Do these steps to configure the offset adjustment:

Connect a signal source to the input and a power meter or spectrum

analyzer to the output of the first online converter.

Record the output power.

Force a backup of the first online unit.

Adjust the offset until the output power matches what was recorded in

Step 2.

Restore the online unit, and then repeat these steps for the other online

units.

comprise your redundancy system.
