The ARRIS SG4‐R‐* receivers feature a built‐in microprocessor for monitoring the optical power, module current, and module enable status. An optical power DC voltage test point, along with a wave‐length selection jumper facilitates accurate measurements of input power. A –20 dB test point enables you to measure carriers throughout the forward band, and gain adjustments are made with a JXP style interstage pad. Output slope is generated by the Linear Midstage Equalizer (LME) plug‐in that is can be changed by removing the receiver cover. Module status indicators help reduce troubleshooting time, and the SG4‐R‐* can be hot‐swapped in the field, providing true plug and play functionality.
