The Atlas Distribution Amplifier is a high quality cost effective signal distribution amplifier that is available in a variety of different configurations. Most configurations provide five outputs and one buffered loop through output from one input signal. Two sets of LED indicators, visible on the front and rear panels, provide an indication for the presence of power and input signal.
All current configurations of the Atlas DA operate on +15 VDC, which is supplied to the unit via a coaxial type power connector. The Atlas DA is supplied with a universal input 95-265 AC power supply to provide the +15 VDC to the unit, however the user may provide power ranging from +15 to +18 volts to the unit.
There are currently three versions of the Atlas DA available at the time of this writing. These are listed as follows:
Model 110-100-1 10 MHz sine DA, one in, six out
This version accepts a 10 MHz sine wave that ranges in power from 0 dBm to 20 dBm and provides five adjustable outputs and one fixed output. The five adjustable outputs can provide a gain factor ranging from –5dB to +12dB and provide a maximum output level of 15 dBm into a 50 ohm load. Each of the five output signals are adjustable by a adjustment potentiometer located near each BNC output connector. The sixth non-adjustable output is available to provide an output signal for another DA or piece of equipment. The signal present indicator will illuminate for sine wave input levels above 0dBm. The input is AC coupled into a 50 ohm termination impedance which may be altered by the user to 5K ohms via an internal shunt. The power requirements for a system driving 50 ohm terminated outputs is approximately 400 mA at 15
VDC.
Model 110-100-2 Wide band TTL/CMOS pulse DA, one in, six out
This version of the Atlas DA accepts a TTL or CMOS level input and provides six pulse outputs capable of delivering TTL levels into a 50 ohm load. The input impedance is factory set to 50 ohms but may be increased to 1K ohms via an internal shut. The LED signal presence indicator will illuminate when a valid TTL input signal is present and includes a circuit to increase the LED illumination period so that a short pulse width (such as a 1PPS from a GPS receiver) are visibly indicated. The power indicator illuminates when power is applied to the unit. The maximum frequency supported by this unit is 60 MHz.
Model 110-100-3 Wide band sine to square DA, one in, five out
This version is designed to accept a sine wave input signal ranging from 0 to 20 dBm and provides five square wave outputs capable of driving TTL levels into a 50 ohm terminated load.
