PTS-SAASM - GPS SAASM based network ready master clock with disciplined Rb Oscillator0 pages

PTS-SAASM
Network Ready Precision Time System
• GPS Disciplined Atomic Clock
• Network Time Server
• Dual Redundant Version Available
• Complete Remote Network Control using
Standard Web Browser
• SA-ASM GPS Receiver
• 10MHz, 1PPS IRIG B, Serial and Time Codes
• Timing Accuracy < 40ns rms to UTC

The PTS-SAASM is a state of the art frequency instrument offering a wide range of features and time and frequency outputs accurate to < 40ns rms to UTC (USNO)
and 1x10-12 respectively.
This new generation of network appliance is economical
and reliable and offers complete remote control and
monitoring via a web-browser based interface.
The PTS-SAASM can be used in either a single or dual
redundant configuration and in conjunction with one of
Brandywine Communications range of Distribution Amplifiers, such as the FTSU-100.
Applications for the popular PTS-SAASM include central
time and frequency systems, satellite earth stations,
military communication systems, and high availability
network time servers.
An extremely accurate internal rubidium oscillator is
used as the internal time base that drives all the time
and frequency outputs. This rubidium oscillator is disciplined using an advanced control algorithm, ensuring
superior holdover performance. The time constants of
this algorithm are user-adjustable to suit specific applications.
A low cost rack adapter is available (not shown).

The PTS-SAASM utilizes a 12 channel P(Y) code SAASM
GPS receiver. It may also be disciplined to an external
1PPS/HaveQuick time code source.
A 100baseT Ethernet port is provided which is used both for
monitoring and control of the instrument and for Network
Time Protocol. This interface supports both fixed and dynamic IP address assignment via DHCP.
In addition to configuring the PTS-SAASM, the built-in web
browser provides information on GPS, internal monitoring of
time errors, and internal parameters of the atomic oscillator.
The user may set thresholds of any monitored parameter to
trigger an alarm.
A precision 1PPS time mark is available for synchronizing or
calibrating other equipment and the IRIG B serial time code
allows synchronization to be distributed to other computers,
displays, and related equipment requiring precise time.
An ASCII serial port outputs any user-selected time of day
message at a 1/sec rate for synchronizing other equipment.
The same output port may also be configured to output 50
bit/sec BCD time code in accordance with ICD-GPS-060.
A high stability 10MHz sine wave output provides an ultrastable, low phase noise frequency reference derived from an
SC cut crystal that is locked to the rubidium reference.
