General Information
Introduction
This chapter provides a description, performance specifications, optional accessories, pre-
ventive maintenance, and calibration requirements for the Site Master model S251C.
Throughout this manual, the term Site Master will refer to the S251C.
Model Frequency Range Ports
S251C 625 to 2500 MHz 2
Description
The Site Master is a hand held SWR/RL (standing wave ratio/return loss), transmission
gain/loss and Distance-To-Fault (DTF) measurement instrument that includes a built-in
synthesized signal source. The S251C includes a keypad to enter data and a VGA (640 ´
480) liquid crystal display (LCD) to provide graphic indications of SWR, RL (dB) over the
selected frequency range and distance. The Site Master is capable of up to 2.5 hours of con-
tinuous operation from a fully charged field-replaceable battery and can be operated from a
12.5 VDC source. Built-in energy conservation features can be used to extend battery life
over an eight-hour work day.
The Site Master is designed for measuring SWR, return loss, or one-port cable insertion
loss and fault locations of RF components in antenna systems. Power monitoring is avail-
able as an option. Site Master model S251C includes transmission gain or loss (S21) mea-
surements and an optional built-in bias tee. The displayed trace can be scaled or enhanced
with frequency markers or a limit lines. A menu option provides for an audible “beep”
when the limit value is exceeded. To permit use in low-light environments, the LCD can be
back lit using a front panel key.
Standard Accessories
The Software Tools PC-based software program provides a database record for storing
measurement data. Site Master Software Tools can also convert the Site Master display to a
Microsoft Windowsä95/98/2000/ME/NT workstation graphic. Measurements stored in the
Site Master internal memory can be downloaded to the PC, and vice versa, using the in-
cluded null-modem serial cable. Once stored, the graphic trace can be displayed, scaled, or
enhanced with markers and limit lines. Historical graphs can be overlaid with current data,
and underlying data can be extracted and used in spreadsheets or for other analytical tasks.
The Site Master Software Tools program can display all of the measurements made with the
Site Master (SWR, return loss, cable loss, distance-to-fault) as well as providing other func-
tions, such as converting display modes and Smith charts. Refer to Chapter 5, Software
Tools, for more information.

** Fault location is accomplished by inverse Fourier Transformation of data taken with the Site Master. Resolution and
maximum range depend on the number of frequency data points, frequency sweep range and relative propagation veloc-
ity of the cable being tested.
*** Immunity measurement is made in CW mode with incoming interfering signal exactly at the same frequency (worst
case situation). Typical immunity is better when swept frequency is used.
Table 1-2. Performance Specifications (2 of 2)

Preventive Maintenance
Site Master preventive maintenance consists of cleaning the unit and inspecting and clean-
ing 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.
CAUTION: To avoid damaging the display or case, do not use solvents or abra-
sive cleaners.
Clean the RF connectors and center pins with a cotton swab dampened with denatured alco-
hol. 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 good, 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,
not stretched, kinked, dented, or broken.
ESD Precautions
The Site Master, like other high performance instruments, is susceptible to ESD damage.
Very often, coaxial cables and antennas build up a static charge, which, if allowed to dis-
charge by connecting to the Site Master, may damage the Site Master input circuitry. Site
Master operators should be aware of the potential for ESD damage and take all necessary
precautions. Operators should exercise practices outlined within industry standards like
JEDEC-625 (EIA-625), MIL-HDBK-263, and MIL-STD-1686, which pertain to ESD and
ESDS devices, equipment, and practices.
As these apply to the Site Master, it is recommended to dissipate any static charges that
may be present before connecting the coaxial cables or antennas to the Site Master. This
may be as simple as temporarily attaching a short or load device to the cable or antenna
prior to attaching to the Site Master. 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 insure a safe environment for both personnel and equipment.

Chapter 1 General Information

Annual Verification
Anritsu recommends an annual calibration and performance verification of the Site Master
and the OSL calibration components by local Anritsu service centers. Anritsu service cen-
ters are listed in Table 1-2 on the following page.
The Site Master itself is self-calibrating, meaning that there are no field-adjustable compo-
nents. However, the OSL calibration components are crucial to the integrity of the calibra-
tion and therefore, must be verified periodically to ensure performance conformity. This is
especially important if the OSL calibration components have been accidentally dropped or
over-torqued.

Functions and Operations
Introduction
This chapter provides a brief overview of the Site Master functions and operations, provid-
ing the user with a starting point for making basic measurements. For more detailed infor-
mation, refer to Chapter 4, Measurements and Chapter 5, Software Tools.
The Site Master is designed specifically for field environments and applications requiring
mobility. As such, it is a lightweight, handheld, battery operated unit which can be easily
carried to any location, and is capable of up to 2.5 hours of continuous operation from a
fully charged battery. Built-in energy conservation features allow battery life to be extended
over an eight-hour workday. The Site Master can also be powered by a 12.5 VDC external
source. The external source can be either the Anritsu AC-DC Adapter (P/N 40-115) or 12.5
Vdc Automotive Cigarette Lighter Adapter (P/N 806-62). Both items are standard accesso-
ries.
Test Connector Panel
The connectors and indicators located on the test panel are listed and described below.
12.5-15VDC
(1100 mA) 12.5 to 15 Vdc @ 1100 mA input to power the unit or for battery charging.
WARNING
When using the AC-DC Adapter, always use a three-wire power cable connected
to a three-wire power line outlet. If power is supplied without grounding the equip-
ment in this manner, there is a risk of receiving a severe or fatal electric shock.
Battery
Charging Illuminates when the battery is being charged. The indicator automatically shuts off when the battery is fully charged.
External
Power Illuminates when the Site Master is being powered by the external charging unit.
Serial
Interface RS232 DB9 interface to a COM port on a personal computer (for use with the Anritsu Software Tools program) or to a supported printer.
RF Out RF output, 50 Wimpedance, for reflection measurements.
RF In RF input 50 Wimpedance for transmission loss or gain measurement.
RF Detector RF detector input for the Power Monitor.

Front Panel Overview
The Site Master menu-driven user interface is easy to use and requires little training. Hard
keys on the front panel are used to initiate function-specific menus. There are four function
hard keys located below the display, Mode, Frequency/Distance, Amplitude and Sweep.
There are seventeen keypad hard keys located to the right of the display. Twelve of the key-
pad hard keys are dual purpose, depending on the current mode of operation. The dual pur-
pose keys are labeled with one function in black, the other in blue.
There are also six soft keys that change function depending upon the current mode selec-
tion. The current soft key function is indicated in the active function block to the right of
the display. The locations of the different keys are illustrated in Figure 2-1.
The following sections describe the various key functions.
