Troubleshooting
The MG3702xA firmware includes internal diagnostics that self-test most of the internal assemblies. When the
MG3702xA fails self-test, one or more error messages appear on screen to aid in isolating the failure to a
replaceable subassembly or RF component.
Chapter 5, “Troubleshooting” lists and describes the self-test error
messages and provides procedures for isolating MG3702xA failures to a replaceable subassembly or RF
component.
Repair
Most instrument failures are field repairable by replacing the failed subassembly or RF component.
Detailed instructions for removing and replacing failed subassemblies and components are provided in
Chapter 6, “Removal and Replacement Procedures” .
1-9 ESD Requirements
All electronic devices, components, and instruments can be damaged by electrostatic discharge. It is important
to take preventive measures to protect the instrument and its internal subassemblies from electrostatic
discharge.
An ESD safe work area and proper ESD handling procedures that conform to ANSI/ESD S20.20-1999 or
ANSI/ESD S20.20-2007 is mandatory to avoid ESD damage when handling subassemblies or components
found in the MG3702xA instrument.
1-10 Preventive Maintenance
Cleaning LCD Display Touch Screen
The touch screen is protected by a plastic display filter. To clean the display filter, dampen a soft cloth with a
mild soap and water solution. Do not use abrasive cleaners, tissues, or paper towels that can scratch the plastic
surface. Gently wipe the display filter to clean.
Maintain Operating System Integrity
The Microsoft Windows XP operation system on the MG3702xA is configured for optimum performance when
the instrument leaves the factory. To maintain the system’s operating integrity, follow proper Windows
shutdown procedure and DO NOT modify the operating system configuration, the firewall settings, the system
registry, the hard disk drive partitions, or the Anritsu user accounts.
Antivirus Protection
The MG3702xA is tested with Trend Micro antivirus software, but stability is not guaranteed with all
antivirus software. Anritsu recommends connecting the instrument only to a secure network. The user
assumes the responsibility to provide virus protection because this is not supplied with the instrument.
Contact your network administrator for information about your network security and antivirus protection
policies.
Windows Updates
Not all Microsoft updates are compatible with the MG3702xA and, if installed, may affect the performance of
the instrument.
