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,
1/5/10 MPPS, IRIG B 000 (DCLS)
1 PPM, 1 PHPH, 1 PPH
• Time Code Output (IRIG B 120 1kHz amplitude modulated)
• 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.
