HP / Keysight / Agilent 3709A Overview
Designed primarily for service and maintenance in digital microwave radios, the 3709A is a dedicated display for characterizing radio performance and condition by analysis of constellation patterns. Since impairments on a digital radio produce distinctive constellation patterns, the 3709A can provide a fast, straightforward method of diagnosing impairments on both in-service and out-of-service systems.
