1206/7A Configurable Distribution

The ptf 1206A (1U) & ptf 1207A (2U) provide the flexibility of distributing a variety of signals from one highly configurable box With ptf’s quad-bloc distribution cards you can build a system that is tailored to your specific needs. Based on the ptf family of Distribution products, ptf quad-blocs are available for Broadband RF, Digital, Pulse and Modulated IRIG Distribution. Dual input A/B autoswitching capabilities are also available as an option.
The ptf Broadband RF Distribution provides high performance frequency references for laboratory or system use. In most applications the phase noise capability of the ptf Broadband RF Distribution will out-perform the input signal performance to such a degree that no additive phase noise will be noticeable on the outputs. Isolation output to output is ~100 dB and harmonics are < -40 dB. The ptf Digital Signal Distribution is a flexible platform used for distribution of various pulse formats (e.g. 1 PPS, 1 PPM, 10 PPM, etc). The ptf Digital Signal Distribution will also distribute digital timing signals such as IRIG-B DCLS format. Through decades of timing design experience, the ptf team is able to reproduce precision pulse input signals with the minimum of propagation delays, with two stages of input signal buffering to distribute the input signal to 12 separate outputs and insure maximum isolation between individual output signals. The ptf Modulated IRIG Distribution uses at its heart a broadband design combining the latest technology in low noise components, to distribute modulated IRIG signal input to provide separate outputs. The ptf Auto Switch is purpose designed for time and frequency applications where reliability criteria call for redundant RF, Pulse and timing sources. The unit accepts a preconfigured input consisting of either an RF (sine) signal, a pulse (typically 1 PPS), or Timing (IRIG) signals. The primary signal is monitored and automatically switches to the backup channel within ~ 3msec (typical).


The ptf 1206/7A-MC is a configurable distributio0n unit with full remote monitoring and control interface.
The ptf 1206A-MC provides up to 12 output channels, while the ptf 1207A delivers up to thirty six channels of frequency and/or timing references to critical applications such as Satellite Communications, Broadcasting, WiMax, and others.

RF channels include a unique feature of output level monitoring of rms output level, together with an optional gain control allowing each RF channel output level to be independently adjusted.
The unit can optionally accept a pair of two inputs (usually from separate primary and backup sources), and provides auto switching and monitoring of both the inputs and output for signal integrity. In addition RF channels include analog level monitoring. With the auto switch option fitted, if the primary input on any channel fails, the unit will automatically switch to the backup input and indicate a primary signal fault.

Full remote monitoring and control via RS232 and Ethernet interfaces includes telnet, http (web browser), and SNMP protocols.
