Case 2. Backup
Æ
Online unit(s)
1.
With the Backup Unit forced to be the active unit, adjust the Offset Value in the
CONFIG: Redundancy
menu to roughly the difference measured previously. This will
be a positive (+) number.
2.
Toggle between the online and Backup Units as being the active path by forcing and un-
forcing a backup through the Backup Unit’s
CONFIG: Redundancy
Æ
SSPA#1
menu.
Make sure the output levels measured are equal. If necessary, re-adjust the Offset Value
until equal levels are measured. (Note that the Backup Unit total attenuation level as now
indicated in the
CONFIG: Amp
Æ
Attenuation
menu will be equal to the setting of the
Online Unit plus the Offset Value.)
For Example:
Online Unit Output Level
47.00 dBm
Backup Unit Output Level
48.75 dBm
Backup Unit Offset Value
0.00 dBm
Online Attenuation Setting
3.00 dB
AFTER TOGGLING AND ADJUSTING:
Backup Offset Value
+1.75 dB
New Equalized Output Level
47.00 dBm
Backup Attenuation Setting
4.75 dB (3+(+1.75) = 4.75)
