900-Series
Modular Distribution System
• Versatile Low-noise Distribution
• Up to 30 channels available
from each rack
• Ultra low noise and EMC prole
• Flexible conguration and
mounting arrangements
• Auto changeover units for
fully redundant switching
ensures safe, continuous 24/7
operation
• Wide range of modules
available including reference
frequencies, 1PPS timing and a
variety of timecodes

The 900-series distribution ampliers are for local distribution of time code signals, 1PPS
timing signals, sinewave reference frequency to multiple outputs, up to 30 per cabinet.

900-Series Overview

All modules have built in test and can detect faults down to
individual output level.
Alarms are consolidated in the rack PSU module and transmitted
by relay output. Automatic signal source changeover is provided
by some modules. This facility can be controlled manually by a
front panel rotary switch, or remotely via a commercially available
I/O to Ethernet adapter.

The 900 series can be widely congured with distribution of
a variety of reference frequencies, 1PPS timing and various
timecodes.

A 5 MHz to 10 MHz frequency doubler module provides good
quality output signals without the need to use synthesizers or
tracking oscillators.

...

The 900 series units can also be found in many satellite ground
stations, running up/down links from the Poles to the Tropics.

Continuous un-interrupted operation is assured via autochangeover input modules, allowing redundant frequency sources
to be used. Dual, hot-swappable power supply modules may be
tted to provide power redundancy.

.

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.

Up to 30 individually buffered outputs at +13 dBm (1V rms in 50
ohm) is available from one 3U high cabinet.

..

The 900 series is a range of high-reliability modules which are
used to build versatile signal distribution systems. The use of ultralow-noise Power Supplies, enclosed module construction and coaxial 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.
