PRODUCT DESCRIPTION
This customer documentation covers the following products:
DEV 2811
1:8 Distribution Amplifier; 3.2…4.2 GHz; 50 Ohm, SMA (f)
DEV 2813
1:16 Distribution Amplifier; 3.2…4.2 GHz; 50 Ohm, SMA (f)
DEV 2851
1:8 Distribution Amplifier; 10.95…12.75 GHz; 50 Ohm, SMA (f)
DEV 2853
1:16 Distribution Amplifier; 10.95…12.75 GHz; 50 Ohm, SMA (f)
All distribution amplifiers are designed in a way, that the signal applied to the
input port is routed to an amplifier and then split into 8 or 16 output signals.
All products are delivered in a 1 RU chassis, are equipped with female
50 Ohm SMA connectors for the input and output ports, and provide
redundant power supplies.

On the right at the front side of the chassis, three LEDs are located
signalizing the power supply operating status of the device:
"Power Supply 1" LED (1)
If this green LED is on, the first power supply unit provides a secondary
voltage feeding the device partially.
"Power Supply 2" LED (2)
If this green LED is on, the second power supply unit provides a
secondary voltage feeding the device partially.
"Failure" LED (3)
This red LED is on if either the first or the second power supply unit does
not deliver any secondary voltage. The reason for this can be a defective
power supply, a defective primary protection fuse, or a missing primary
voltage.
