The Viavi SCU-1800-FWD-REV-1P Forward & Reverse Sweep Control Unit, 1.218 GHz Forward, Single-User 204 MHz Reverse, 1 Active Reverse Port, is an advanced sweep transceiver offering updated, space saving hardware and simple browser configurability. The headend/hub rack-mounted SCU-1800 provides non-interfering downstream sweep to 1.218 GHz and upstream sweep to 204 MHz on 1 port.

The space-conserving 1RU Sweep Control Unit with a single switchable return sweep port is remotely or locally configurable and the interface is accessible via Ethernet/Internet/Intranet and browser. Improved pulse generation performance provides a pure, clean RF sweep signal with narrower pulses enabling insertion between carriers. Additionally, there is an auto-fill capability in which the sweep points are automatically injected in unoccupied spectrum areas.
