1-2 Instrument Description
The Site Master S331E/S361E is a handheld cable and antenna analyzer designed to make
Return Loss, VSWR, Cable Loss, and Distance-To-Fault (DTF) measurements in the field.
The cable and antenna analyzer also includes 1-port phase and smith chart measurements.
The 2-port transmission measurement option includes two power levels and access to a
built-in 32 volt bias tee (Option 10).
The S332E/S362E is an integrated multi-functional test instrument that eliminates the need
to carry and learn multiple test sets. In addition to the cable and antenna measurements, the
S332E/S362E can be configured to include a Spectrum Analyzer, 2-port Transmission
Measurement, Interference Analyzer with Interference Mapping capabilities, Coverage
Mapping, Channel Scanner, CW Signal Generator, AM/FM/PM Analyzer, PIM Analyzer,
Power Meter, and High Accuracy Power Meter. A GPS receiver can be added to both the
S331E/S361E and the S332E/S362E Site Master models.
The bright 8.4 in TFT color display provides easy viewing in a variety of lighting conditions.
All Site Master models are equipped with a Li-Ion battery delivering more than four hours of
battery life for the S331E/S361E and more than three hours of battery life for the
S332E/S362E Site Masters.
The combination of a touch screen and keypad enables users to navigate menus with the
touch screen and enter numbers with the keypad.
The internal memory is large enough to store approximately 2,000 traces or setups.
Measurements and setups can also be stored in a USB flash drive or transferred to a PC using
the included USB cable. Ethernet connectivity is available using Option 411.
Available Models
Table 1-1 lists the Site Master models described in this User Guide.
Note
Not all after-market USB drives are compatible with the instrument. Many drives
come with a second partition that contains proprietary firmware. This partition must
be removed. Only one partition is allowed. Refer to the individual manufacturer for
instructions on how to remove it. You may also try reformatting a drive that
contains a single partition using FAT32 format.

Site Master User Guide PN: 10580-00252 Rev. K 1-3
Available Options
Available options for the Site Master are shown in Table 1-2.
1. Requires External Power Sensor.
2. Requires Option 31.
1-3 Calibration and Verification
Anritsu recommends annual calibration and performance verification by local Anritsu
service centers. The Cable and Antenna Analyzer mode requires calibration standards for
OPEN, SHORT, and LOAD (OSL) or InstaCal module, which are sold separately.
The Site Master is self-calibrating and there are no field-adjustable components. The OSL
calibration components are crucial to the integrity of the 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.

1-4 Instrument Care and Preventive Maintenance General Information
1-4 PN: 10580-00252 Rev. K Site Master User Guide
1-4 Instrument Care and Preventive Maintenance
Instrument care and preventive maintenance consist of cleaning the unit and inspecting and
cleaning the RF connectors and all accessories. Clean the instrument with a soft, lint-free
cloth dampened with water or water and a mild cleaning solution.
Connector Care
Clean the RF connectors and center pins with a cotton swab dampened with denatured
alcohol. Visually inspect the connectors. The fingers of the N(f) connectors and the pins of the
N(m) connectors should be unbroken and uniform in appearance. If you are unsure whether
the connectors are undamaged, gauge the connectors to confirm that the dimensions are
correct. Visually inspect the test port cable(s). The test port cable should be uniform in
appearance, and not stretched, kinked, dented, or broken.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
Type-N connectors. The recommended torque is 12 lbf·in to 15 lbf·in (1.36 N·m to 1.70 N·m).
Inadequate torque settings can affect measurement accuracy. Over-tightening connectors can
damage the cable, the connector, the instrument, or all of these items.
Visually inspect connectors for general wear, cleanliness, and for damage such as bent pins or
connector rings. Repair or replace damaged connectors immediately. Dirty connectors can
limit the accuracy of your measurements. Damaged connectors can harm the instrument.
Connection of cables carrying an electrostatic potential, excess power, or excess voltage can
damage the connector, the instrument, or both.
Connecting Procedure
1. Carefully align the connectors. The male connector center pin must slip concentrically
into the contact fingers of the female connector.
2. Push connectors straight together. Do not twist or screw them together. A slight
resistance can usually be felt as the center conductors mate.
3. To tighten, turn the connector nut, not the connector body. Major damage can occur to
the center conductor and to the outer conductor if the connector body is twisted.
4. If you use a torque wrench, initially tighten by hand so that approximately 1/8 turn or
45 degrees of rotation remains for the final tightening with the torque wrench.
Relieve any side pressure on the connection (such as from long or heavy cables) in order
to assure consistent torque. Use an open-end wrench to keep the connector body from
turning while tightening with the torque wrench.
Do not over-torque the connector.
Disconnecting Procedure
1. If a wrench is needed, use an open-end wrench to keep the connector body from turning
while loosening with a second wrench.
2. Complete the disconnection by hand, turning only the connector nut.
3. Pull the connectors straight apart without twisting or bending.
Caution To avoid damaging the display or case, do not use solvents or abrasive cleaners.
