2.1.5.5 Purge Fault Log Operation
Clicking on this button will bring up a dialog window asking for fault log purge confirmation. If
“Yes” is clicked, the entire contents of the existing fault history file will be deleted. Fault history
data is written to a file named FaultHistory.txt . The fault history file is a standard text file, which
can be read/opened with a text editor program such as Notepad. It is recommended that the
fault history file be archived and purged as a regular part of the normal system maintenance.
The file can either be copied or moved to some external storage medium.
2.2 Amplifier Gain Check Procedure
The Amplifier Gain Check procedure (refer to Figures 11, 12, 13, 14, 15, 16 and 17) allows the
RF output power contribution of each individual amplifier to be checked. The procedure walks
the user through a step-by-step process with on-screen instructions for each step. The
procedure can be canceled and restarted at any time. Currently, it is not possible to go
backwards (backup one or two steps). The basic procedure is as follows:
• Set upconverter to ALC Manual mode
• Raise ALC Manual value to adjust power between 50 and 100% output power.
• Turn each amp off, record power drop.
• Turn each amp back on.
• Repeat previous two steps for each of the remaining amps.
