AC6993 Transponder
The AC6993 is a DOCSIS 3.1 frequency range compatible CATVisor/HMS transponder containing an RF modem and a level measurement unit.
The AC6993 transponder can be used to add remote monitoring and control, ALSC, automatic forward and return path alignment, forward path spectrum analyser, return path ingress analyser and extended frequency range return path pilot generator to AC3x10 amplifiers.
Features at a glance:
- Compatible with: AC3010, AC3210
- Plug-in unit with no additional cables
- Lid status monitoring with light sensor
- Pushbutton for true Plug-and-Play: full automatic alignment of both forward and return path signal paths
