1-2 Instrument Description
The Site Master S331L is a one-port,2MHzto4GHzhandheldcable
and antenna analyzer designed to make Return Loss, VSWR, Cable
Loss, Distance-To-Fault (DTF), and power measurements in the field.
The analyzer is an integrated multi-functional test instrument that
eliminates the need to carry multiple test sets. In addition to the cable
& antenna measurements, the instrument includes an integrated
InstaCal module, internal power meter, and high accuracy external
USB power meter mode utilizing Anritsu’s external USB sensors
(sold separately).
The bright, high-resolution, 800 pixel by 480 pixel 7 inch color display
provides easy viewing in a variety of lighting conditions. The
combination of a resistive touchscreen and keypad enables users to
navigate menus with the touchscreen and enter text or numbers
directly. A user-editable EZ Name Matrix allows users to configure
complex sweep names quickly, saving hours of valuable time daily.
The Site Master is equipped with factory installed Li-Ion batteries
delivering more than eight hours of battery life when fully charged.
The internal memory is large enough to store more than 1,000 files.
Files can be any combination of measurement files, setup files, or screen
shots. Files can also be saved or copied to a connected USB flash drive.
Measurements can be transferred to a PC using the supplied USB cable
or with a USB flash drive.

General Information 1-2 Instrument Description
Battery Information
The batteries that are supplied with the Site Master may need charging
before use. They can be charged using either the AC-DC Adapter or the
DC adapter. Refer to “Status Tool Bar” on page 2-17 for a description of
battery symbols. The batteries are charged in the instrument and only
removed for replacement.
The Site Master batteries are installed at the factory and can be
replaced by the user. Refer to Chapter 10, “Battery Replacement” for
information on replacing the batteries. The batteries are charged with
the included AC/DC adapter.
Note
Use only Anritsu-approved batteries, adapters, and chargers
with this instrument.
The batteries will charge at a faster rate when the instrument
is turned off or is set to standby mode. Charging the batteries
while the instrument is running will take a longer time to reach
a full charge.
To prolong the useful battery life, the internal charging circuit
monitors each battery’s temperature. Normal charging occurs
when the battery temperature is between 0 °C and 45 °C.
Charging is paused if the internal battery temperature is
beyond this range.
Caution
When using the Automotive Cigarette Lighter Adapter, always
verify that the supply is rated for a minimum of 40 Watts @
12 VDC, and that the socket is clear of any dirt or debris. If
the adapter plug becomes hot to the touch during operation,
discontinue use immediately.
Note Anritsu Company recommends removing the battery for
long-term storage of the instrument.

1-3 Instrument Care and Preventive Maintenance General
1-3 Instrument Care and Preventive
Maintenance
Site Master preventive maintenance consists of cleaning the unit and
inspecting and cleaning the RF connectors on the instrument and all
accessories. Clean the Site Master with a soft, lint-free cloth dampened
with water or water and a mild cleaning solution.
Clean the RF connectors with a cotton swab dampened with denatured
alcohol. Visually inspect the connectors. If you are unsure whether the
connectors are undamaged, gauge the connectors to confirm that the
dimensions are correct.
Carefully inspect the test port cable. The cable should be uniform in
appearance, and not stretched, kinked, dented, or broken. A defective
test port cable is the most common cause of unreliable or erratic
measurements. Extra care should be exercised to ensure the test port
cable remain in good condition.
ESD Caution
The Site Master, like other high performance instruments, is
susceptible to electrostatic discharge (ESD) damage. Coaxial cables and
antennas may build up a significant static charge, which may damage
the Site Master. To prevent ESD damage, users are advised to connect a
short to either end of the cable before connecting the cable to the Site
Master. If no short is available then a termination (load) may be used.
Site Master operators must always be aware of the potential for ESD
damage and take all necessary precautions. Operators should exercise
practices outlined within industry standards such as JEDEC-625
(EIA-625), MIL-HDBK-263, and MIL-STD-1686; which pertain to ESD
and ESDS devices, equipment, and practices. It is important to
remember that the operator may also carry a static charge that can
cause damage. Following the practices outlined in the above standards
will ensure a safe environment for both personnel and equipment.
Caution To avoid damaging the display or case, do not use solvents or
abrasive cleaners.

General Information 1-4 Calibration and Annual Verification
RF Input Warning
The Anritsu Site Master is a sensitive measuring instrument designed
to measure low power levels. Avoid damaging this sensitive circuitry by
observing the maximum input levels printed on the instrument
connector labeling and specified in the product technical data sheet.
Depending on your instrument hardware revision, typical maximum
input is +42 dBm or +23 dBm (±50 VDC). Check the RF Out/Reflect In
connector labeling on the unit. The maximum RF input could be less if
additional features, such as a preamplifier, are in use. Review the
product technical data sheet or Anritsu website for recommended
components and accessories that can help you protect your instrument.
These include a variety of adapters, attenuators, filters, and RF
detection accessories.
1-4 Calibration and Annual Verification
The Cable and Antenna Analyzer requires user performed calibration
before making line sweep measurements. Calibration can be quickly
and easily performed at the end of a test port cable (not included) using
the built-in InstaCal module. External OPEN, SHORT, and LOAD
(OSL) calibration method is another option and requires Anritsu OSL
components which are sold separately. Flex Cal is supported using
either calibration method. Refer to Chapter 7, “Calibration” for
additional information.
The external InstaCal Calibration Modules (ICN50 and ICN50B) are
NOT compatible with the Site Master S331L.
Anritsu recommends an annual calibration and performance
verification of the Site Master by local Anritsu service centers. Anritsu
service also recommends a semi-annual verification of OSL calibration
components.
Note
Anritsu recommends allowing the S331L to warm up for
5 minutes to typical operation temperature before calibrating.
The instrument will require a new calibration if the internal
instrument temperature changes more than ±20 ºC after
calibration.

1-8 PN: 10580-00321 Rev. M S331L UG
1-5 Secure Environment Workplace General Information
The Site Master is self-calibrating and there are no field-adjustable
components. The OSL calibration components and the Internal
InstaCal are crucial to the integrity of the user calibration. As a result,
they must be verified periodically to ensure performance conformity.
This is especially important if the OSL calibration components have
been accidentally dropped or over-torqued.
1-5 Secure Environment Workplace
This section describes the types of memory in the Site Master, how to
delete stored user files in internal memory, and recommended usage in
a secure environment workplace.
Site Master Memory Types
The instrument contains non-volatile disk-on-a-chip memory,
EEPROM, and volatile DRAM memory. The instrument does not have a
hard disk drive or any other type of volatile storage memory.
EEPROM: This memory stores the model number, serial number, and
calibration data for the instrument. Also stored here are the user-set
operating parameters such as frequency range. During the master reset
process, all operating parameters that are stored in the EEPROM are
set to standard factory default values.
RAM Memory: This is volatile memory used to store parameters needed
for the normal operation of the instrument along with current
measurements. This memory is reset whenever the instrument is power
cycled. Standby mode does not reset this memory.
External USB Flash Drive (not included with the instrument): This
memory can be selected as the destination for saved files. The user can
also copy the contents of the internal memory to the external flash
memory for storage or data transfer. The external USB flash drive can
be reformatted or sanitized using software on a PC.
Refer to Chapter 8, “File Management” for additional information on
saving and copying files to the USB flash drive.
Note The screen images on your instrument or computer may vary
from what is shown in this User Guide.
