Product Data Sheet 900-series 900-series, 2804, TO-16; Pendulum Instruments Keeps The Galileo Project on Time 900-series Modular Distribution System Overview
The 900 series is a range of high-reliability modules which are used to build versatile signal distribution systems. The use of ultra-low-noise Power Supplies, enclosed module construction and co-axial cable for interconnections means that the units have excellent noise, emissions and immunity characteristics.
The mainframe is suitable for 19" rack, desktop or wall mounting. Typical applications are in installations where ‘round the clock’ reliability is a must.
Examples include manufacturing plants for items such as mobile communications equipment and cellular base stations, both military and commercial. More generally the 900 series has applications in development
laboratories,
support workshops and calibration areas.
The 900 series units can also be found in many satellite ground stations, running
up/down links from the Poles to the Tropics. The 900 series can be widely configured with distribution of a variety of reference frequencies, 2.048 MHz (G.703) clock signals, 1-pps timing and various timecodes. Up to 30 individually buffered outputs at +13 dBm (1V rms in 50 ohm) is available from one 3U high cabinet. Continuous un-interrupted operation is assured via auto-changeover input modules, allowing redundant frequency sources to be used.
All modules have built in test and can detect faults down to individual output level.
