(switchable with bridging plugs)
■Built-in variable attenuators (delivery condition return path:
max. attenuation) and variable equaliser
■LED to indicate operational mode
■Test socket on output -20 dB (with directional coupler)
■Test socket on input -20 dB (Return path 5 – 204 MHz)
■Test sockets are terminated with the EMK 03 in the delivery
status
■For indoor installation
■Conform to: EN 60728-11, EN 50083-2 und EN 32368-1
