99--Fault Resistant Timing Distribution System Requirements

This notice is being cancelled and is being reissued under NAAJAF400-2-10066.FAULT RESISTANT TIMING DISTRIBUTION SYSTEM REQUIREMENTS Provide Timing Distribution Systems (TDS) consisting of two (2) chassis types. The first type shall distribute frequency signals with a 5MHz input and a minimum of 12 cards with 48 - 5 MHz outputs. The second chassis type shall distribute IRIG B time code data and a minimum of 12 cards with 48 - IRIG B time code outputs. Each chassis shall allow to daisy chain output to additional distribution chassis. The contractor shall include six spare power supply and six spare fault sensing modules as part of the TDS. The specific requirements for each type of chassis are set forth below: 1. Each chassis shall be fault tolerant including hot swapable: power supplies (two) and distribution cards. Each chassis shall include a fault sense card and separate bus structure for up to four different timing signals. Physical characteristics. Each timing distribution chassis shall be allow for signal monitoring on the front and input/output on the rear. Each chassis shall have modular plug-in units for ease of replacement and/or expansion and be rack mountable in a standard 19-inch width electronic equipment rack and with a height of no more than 5.25 inches. 2. Controls & indicators. All chassis/module test points and indicators shall be accessible to the operator from the front panel. As a minimum, the following controls and indicators shall be provided: Input signal monitor - Each input signal shall be monitored. The module shall have an indicator or a test point. Output signal monitor - Each output signal shall be monitored. Each output shall have an individual indicator or a test point for each output. Each distribution card shall have a fault indicator. Output signal level - Each output shall be 1 Vrms (+13 dBm) + 2 dB into a 50 ohm resistive load. Power on - a lighted indicator(s) (green) shall indicate AC power is on. The indicator(s) shall be located on the front of each power supply. Power fault - a (Red) fault indicator shall be provided on each power supply. 3. Input characteristics. Physical. Each input shall be via a standard female BNC connector. Electrical. Each chassis shall have multiple inputs from either a GPS based or alternate source chassis. 4. Output characteristics. Physical. Each chassis shall contain at least 12 distribution cards with at least 4 channels per card. Each output shall be via a standard female BNC connector on the back of the chassis. Signal Level. Each distribution output shall be at least 1 Vrms (+13 dBm) + 2 dB into a 50 ohm impedance. Isolation. Each output shall have an isolation of > 60 dB from each of the other outputs. Sixteen (16) each are needed. This is a firm-fixed price award. All special specifications have been included in this announcement
