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.

1-8 Service Strategy
This section provides an overview of the VNA service strategy and available service facilities. It also provides
references to the information in various locations in this manual needed to accomplish the required service
functions.
Functional Assembly Level Troubleshooting
The VNA modular design, extensive built-in diagnostics, and automated service tools are designed to support
fast exchange of functional assembly level repairs.
Failed Assemblies
Failed assemblies are not field repairable. Once an assembly is found to be faulty, it should be returned to an
authorized Anritsu Service Center for exchange. Refer to the description of the “Exchange Assembly Program”
on page 2-1 in Chapter 2, “Replaceable Parts”.
Troubleshooting
The procedures for troubleshooting a failed VNA are described in Chapter 7, “Troubleshooting”.
Internal Hardware Adjustments and Calibrations
There are five automated internal hardware field calibrations. Two of them are used to characterize the VNA
frequency and power generation sub-systems. These calibrations insure fast, consistent phase lock of system
frequencies and proper compensation, leveling, and flatness of system power at the front panel test ports.
To conduct these calibrations, you need only connect the appropriate test equipment (counter or power meter)
to the VNA and initiate the calibration. The VNA will control itself and the externally connected test
equipment to perform measurements and store calibration constants in its internal battery backed RAM
(BBRAM).
The procedures for adjusting the VNA are described in Chapter 6, “Adjustments”.
Internal Service Log
The VNA continuously monitors itself for proper operation. Should a failure occur, it notifies the user via a
failure message on the display screen. (In remote-only operation, it also sets the GPIB Status Byte, if enabled.)
It also writes the error message along with some data pertinent to the failure to an internal service log stored
in battery backed memory.

1-9 Service Support Chapter 1 — General Information
1-4 PN: 10410-00303 Rev. A Lightning 37xxxE MM
The service log can be checked at any time to view (without erasing) all error messages that were written into
it. It is capable of storing more than 30 pages of service messages and data. If necessary, the VNA will
automatically remove the oldest errors first to make room for new errors.
To check the contents of the service log, use the procedure described in Chapter 4, “Operational Performance
Tests”.
System Test/Certification
Quick operational checkout of the system may be accomplished by the system user or for incoming inspection
purposes using the “Operational Checkout” chapter in the Lightning 37xxxE Series VNA Operation Manual –
10410-00300. Those procedures are useful in quickly verifying that the instrument’s primary measurement
functions are operational and stable. Full operational testing of the system is detailed in
Chapter 4, “Operational Performance Tests”.
These tests should be performed annually or whenever a measurement problem is suspected. Verification of
the system’s measurement accuracy and other key performance parameters may be done using the procedures
in Chapter 5, “System Performance Verification”. This should be performed annually or whenever a
measurement problem is suspected.
Servicing Specially Modified Instruments
Instruments with customer-requested special modifications performed by Anritsu will have an identifying
Specials Modification number printed on the rear panel. This number will be preceded with the letters SM,
that is, SM1234 is special modification number 1234.
Special instruments may have service requirements different from those specified in this manual. Contact your
local Service Center if you need more information when servicing such instruments.
