ptf 3207A Time and Frequency System Description and Features
The ptf 3207A provides high-precision time and frequency signals. Its modular design allows factory
customization for a wide range of applications. In its standard configuration, the ptf 3207A functions as
a stand-alone unit which can receive an IRIG time code input, 10MHz input, or 1PPS input,
synchronizes its internal oscillator to that input, and produces time code and frequency outputs.
When paired with its internal timing-optimized GNS receiver, the ptf 3207A provides 1x10-12
frequency output accuracy, and better than 30 nS RMS accuracy to UTC (USNO). The ptf 3207A is
available in a 19-inch 1U or 2U chassis with rack mount ears for installation.
This new range of Time and Frequency Clocks incorporates a flexible architecture to meet the most
demanding clock synchronization requirements. The ptf 3207A incorporates a dual redundant
reference source design that enables high-availability of the clock source. To achieve high-availability,
the user configures the ptf 3207A with dual independent GPS receivers and antennas, or with one GPS
antenna/receiver and one time code or 1PPS reference. In addition, the 1U chassis, when configured
with two modules, provides dual redundancy and distribution in a single 1U unit.
Optional oscillator upgrades provide enhanced short term stability when locked to a reference source,
and improved holdover ‘flywheeling’ when a reference source is unavailable.
The ptf 3207A-TCG configuration is designed to provide additional time code features, in particular this
configuration offers count up/down capability and an additional I2C interface to provide remote
control for loading preset count up/down time, start, hold, and direction (up/down).
Features and Options
Three user interfaces are available for managing the ptf 3207A:
• The web interface, available using a browser connected to the Ethernet port
• The command line interface, available from the serial port and standard Ethernet port (telnet)
• The keypad/display interface, available on the front panel of the ptf 3207A
In addition the unit includes SNMP v1,2,and 3.
Go to Contents Precise Time and Frequency, LLC., 50L Audubon Road, Wakefield, MA 01880, USA ptf 3207A rev U
The ptf 3207A’s modular design allows factory customization for a wide range of applications. The
following range of features are available in the standard configuration:
• Voltage-controlled temperature-compensated crystal oscillator (VCTCXO)
• 1 PPS Output
• Digital Output 1/10/100 PPS, 1/10/100 kPPS, (PPS=Pulses Per Second)
1/5/10 MPPS, IRIG B 000 (DCLS)
1 PPM (minute), 1 PHH (half hour), 1 PPH (hour),
Pulse widths are settable in 100 nano second steps
• Time Code Output (IRIG B 120 1kHz amplitude modulated) , NASA 36
• Count down pseudo IRIG B time code output (ptf 3207A-TCG only)
• Alarm clean contact Output
• Time Code Input (AM or DC: IRIG- B)
• Auxiliary Reference Frequency Input (10 MHz)
• Ethernet Port (10/100 Base-T)
• Command Line Interface (Telnet and Serial Port)
• Simple Network Management Protocol (SNMP)
• Web Interface (HTML)
• Vacuum florescent display, 19-button keypad
• 90-264 VAC
In addition, the ptf 3207A’s standard features can be expanded with the following optional
configurations:
• GPS C/A Receiver References
• Network Time Server (NTP)
• T1/E1 Output
• RS485 Control/Monitor interface
• Oscillator Options: OCXO, ULNO, Rubidium
• DC Power Supplies for 18 to 72, and 48 VDC applications
• Redundant power supplies
Optional oscillator upgrades provide enhanced short term stability when locked to a reference source,
and improved holdover ‘flywheeling’ when a reference source is unavailable.
