Safety-2 PN: 10370-10367 Revision: H MG369xB
For Safety
Warning Always refer to the operation manual when working near locations at which
the alert mark, shown on the left, is attached. If the operation, etc., is
performed without heeding the advice in the operation manual, there is a
risk of personal injury. In addition, the equipment performance may be
reduced.
Moreover, this alert mark is sometimes used with other marks and
descriptions indicating other dangers.
Warning
When supplying power to this equipment, connect the accessory 3-pin
power cord to a 3-pin grounded power outlet. If a grounded 3-pin outlet is
not available, use a conversion adapter and ground the green wire, or
connect the frame ground on the rear panel of the equipment to ground. If
power is supplied without grounding the equipment, there is a risk of
receiving a severe or fatal electric shock.
Warning
This equipment can not be repaired by the operator. Do not attempt to
remove the equipment covers or to disassemble internal components.
Only qualified service technicians with a knowledge of electrical fire and
shock hazards should service this equipment. There are high-voltage parts
in this equipment presenting a risk of severe injury or fatal electric shock to
untrained personnel. In addition, there is a risk of damage to precision
components.
Warning
Use two or more people to lift and move this equipment, or use an
equipment cart. There is a risk of back injury if this equipment is lifted by
one person.
Caution
Electrostatic Discharge (ESD) can damage the highly sensitive circuits in
the instrument. ESD is most likely to occur as test devices are being
connected to, or disconnected from, the instrument’s front and rear panel
ports and connectors. You can protect the instrument and test devices by
wearing a static-discharge wristband. Alternatively, you can ground
yourself to discharge any static charge by touching the outer chassis of the
grounded instrument before touching the instrument’s front and rear panel
ports and connectors. Avoid touching the test port center conductors
unless you are properly grounded and have eliminated the possibility of
static discharge.
Repair of damage that is found to be caused by electrostatic discharge is
not covered under warranty.

General Information Level of Maintenance
MG369xB MM PN: 10370-10367 Rev. H 1-3
1-9 Level of Maintenance
Maintenance of the MG369xB consists of:
•Troubleshooting the instrument to a replaceable subassembly or RF component
•Repair by replacing the failed subassembly or RF component.
•Calibration
•Preventive maintenance
Troubleshooting
The MG369xB firmware includes internal diagnostics that self-test most of the internal assemblies. When the
MG369xB 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 MG369xB 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”.
Calibration
The MG369xB may require calibration after repair. Refer to Chapter 4, “Adjustment” for a listing of
requirements and procedures.
Preventive Maintenance
Preventive maintenance on the MG369xB consists of cleaning the fan honeycomb filter, described in
Section 1-11.
1-10 ESD Requirements
The MG369xB contains components that can be easily damaged by electrostatic discharge (ESD). 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
MG369xB instrument.

Preventive Maintenance General Information
1-4 PN: 10370-10367 Rev. H MG369xB MM
1-11 Preventive Maintenance
The MG369xB must always receive adequate ventilation. A blocked fan filter can cause the instrument to
overheat and shut down. Check and clean the rear panel fan honeycomb filter periodically, especially in dusty
environments. Clean the filter as follows.
1. Turn off the synthesizer and disconnect the power cord from the instrument.
2. Use a #3 screwdriver to remove the four screws that fasten the filter guard to the rear panel
(see Figure 1-1). Retain the screws for reassembly.
3. Vacuum the honeycomb filter to clean it.
4. Reinstall the filter guard.
5. Fasten the filter guard to the rear panel using the four screws that were removed in step 1.

General Information Startup Configurations
MG369xB MM PN: 10370-10367 Rev. H 1-5
1-12 Startup Configurations
The MG369xB comes from the factory with a jumper across pins 2 and 3 of the A2 microprocessor PCB
connector JP1 (Figure 1-2). In this configuration, connecting the instrument to line power automatically places
it in operate mode (front panel OPERATE LED on).
The startup configuration can be changed so that the signal generator comes up in standby mode (front panel
STANDBY LED on) when it is connected to line power. Change the startup configuration as follows:
1. Disconnect the instrument from line power.
2. Remove the top cover from the MG369xB and A2 PCB. Refer to Section 6-4 and Section 6-6 for
instructions.
3. Locate the connector JP1 and remove the jumper from across pins 2 and 3. Refer to Figure 1-2 below.
4. Install the jumper across pins 1 and 2 of the connector JP1.
5. Install the top covers and connect the signal generator to line power. The instrument should come up in
standby mode.
