The Agilent/Keysight 87075C is a 75-ohm multiport test set that extends network analyzer capabilities for high-volume characterization of RF and microwave devices. It eliminates the need for repeated RF interconnections by measuring all signal paths and ports of a device under test in a single connection setup. This approach reduces operator fatigue, minimizes connection errors, and significantly improves test throughput.

– Key Features
Solidstate switching delivers reliable, fast port selection. The SelfCal technique reduces system calibration time by up to 20 times compared to traditional methods—typical monthly calibration cycles can be compressed to approximately 1 hour. When paired with a compatible network analyzer, the 87075C forms a fully specified measurement system with consistent accuracy and correlation across test setups.
– Typical Applications
Designed for production testing of multiport RF components including taps, splitters, and amplifiers. Cable TV device manufacturing and similar high-volume test environments benefit from reduced setup time and improved measurement repeatability.
– Compatibility & Integration
Works with Agilent 8711C-Series, 8712C, 8713C, 8714C, and ENA-L network analyzers. Control via parallel port interface cable (8120-6818), GPIB through compatible analyzer, or LAN for integration with test-process management software. IBASIC programming support included.
