AT&T SLW2500 Installation and Operation Manual

A driver-hybrid amplifies the signal to a sufficiently high level to feed up to four power-doubling

output stages. These output hybrids use enhanced gallium arsenide (GaAs) types for higher

station output at low distortion. Plug-in facilities are available ahead of each output stage for

individual equalizer boards. These can be installed to customize the tilt for the various ports.

Minus 20 dB directional test points are available at various points in the signal paths of the

node. Because these test points are 75-ohm source impedance, special test probes are not

required.

Model JXP-* attenuator pads are used for adjusting signal levels within the signal path.
