of delivery, and support information.

CHAPTER 2•Instruction Manual XYZ 5
CHAPTER 2

The TSync-PCIe board with optional internal GNSS receiver is a complete synchronized time
code processor package that supports multiple prioritized timing inputs. When an input is lost,
the unit automatically switches to the next input in order of priority.
The disciplined onboard oscillator is phase-locked to an external timing input, providing 5ns
resolution time. This 10-MHz oscillator, central to the TSync-PCIe timing functions, uses the last
known reference to increment (“freewheel”) in the absence of a timing input.
The TSync-PCIe generates an IRIG AM and DCLS output pair, as well as 10-MHz sine wave and
1PPS outputs.
The board’s four programmable inputs may be used as event capture inputs, dedicated to your
time-tagging applications. Four user-programmable alarm and frequency outputs are also
provided. Programmable output functions include a periodic pulse or “heartbeat,” square
wave, and programmable start/stop time “alarm” output.
Key to the TSync-PCIe's functionality is the ability to generate interrupts. Using one of the many
available Spectracom driver packages, you may configure your card using interrupt-driven
algorithms to support your unique applications.
2.1 General Information about GPS and GNSS
The United States government operates a set of approximately 32 satellites, collectively known
as the "GPS Constellation" or "GPS Satellites." Each satellite has an internal atomic clock and
transmits a signal specifying the time and satellite position. On the ground, the GPS receiver
determines its position (longitude, latitude and elevation) and the time by decoding the signals
simultaneously from at least four of the GPS satellites. Each satellite transmits a signal in the L1
band at a frequency of 1575.42MHz. When power is first applied, the GPS receiver begins
searching for the satellites. This process can take a few minutes, as the receiver iteratively loc
ates satellites, refines its position, and determines for which satellites to search.
The GPS receiver retains the last known position when the power is switched off. This results in
faster satellite acquisition the next time it is switched on. If the antenna has been moved more
than a few miles, however, acquisition time will be slightly longer because it must first re-com
pute the position.
The US military has adopted the selective availability anti-spoofing module (SAASM) for all
new GPS deployments. SAASM GPS receivers make use of encrypted signals transmitted via L1
and L2 frequencies. Only authorized users can use SAASM GPS receivers.
This unit is capable of using other Global Navigation Satellite Systems (GNSS) alongside, or
instead of, GPS: The Russian GLONASS system is fully operational with 24satellites each trans
mitting at a frequency in the L1 band between 1598and 1606MHz. This GPS/GLONASS fre
quency diversity offers improved performance in some environments when using dual-mode
GPS+GLONASS receivers. Other benefits are system redundancy and the availability of addi
tional satellites when using GPS and GLONASS together.
2.2 Spectracom GNSS Receiver
This TSync-PCIe system is available with an optional integrated GNSS receiver.
6CHAPTER 2•Instruction Manual XYZ Rev. R
2.1 General Information about GPS and GNSS

The board supplies 5VDC through the receiver module to the external antenna via the coaxial
cable (antenna and cable are sold separately).
The unit can also be operated with an external GNSS receiver (i.e., the receiver is built into the
antenna housing). In this case, the board supplies 12VDC to the receiver/antenna through its
data communications cable.
NOTE – The GNSS receiver and the Spectracom GNSS antenna are compatible
with GLONASS. Utilizing this functionality does not require any additional setup
by the user. In this manual, references to GPS also refer to GLONASS, unless
stated otherwise.
NOTE – The TSync board is compatible with a SAASM receiver for authorized
users. Instructions specific to SAASM operation are provided in a spearate
manual. The SAASM receiver is not compatible with GLONASS.
2.3 Unpacking
Unpack the equipment and inspect it for damage. If any equipment has been damaged in
transit, or you experience any problems during installation and configuration of your Spec
tracom product, please contact your closest Spectracom Customer Service Center (contact
information see "Support" on the next page.)
Caution – Electronic equipment is sensitive to Electrostatic Discharge (ESD).
Observe all ESD precautions and safeguards when handling the unit.
2.4 Product Inventory
Before installing the board, please verify that all material ordered has been received:
All boards are shipped with a break-out cable and a CD containing system drivers, and this
user manual.
Boards equipped with internal GNSS receivers are shipped with an SMA-to-Type-N-RF adapter
cable.
Boards equipped with an external GNSS receiver are shipped with a 100-foot antenna cable
and a mini-DIN to DB-15 adapter cable.
Extension cables for the external GNSS receiver are available in 100-foot lengths. The max
imum total length is 500feet. The connectors on the extension cables are not weatherproof:
2.3 Unpacking
CHAPTER 2•Instruction Manual XYZ Rev. R7

Only the first 100 feet can be outdoors. The cable consists of several twisted pairs (not the
coaxial cable) and a foil shield.
Should there be any discrepancy between items ordered and items shipped and received,
please contact your closest Spectracom Customer Service Center.
