VM
: Continuous Wave Distribution Amplifier
This module distributes and amplifies one continuous wave input to six outputs. A seventh
spare output stage together with a change-over relay at each of the six outputs enables
complete redundant output signals. Each output stage is monitored for signal failures. Alarm
outputs are available as SNMP, GPI, LEDs and lamps.
