– Typical Applications
The Y1139A serves engineers and technicians requiring custom cabling solutions where standard off-the-shelf cables do not satisfy specific interconnect requirements. Common use cases include test setups demanding non-standard cable lengths, custom wiring topologies, or specialized termination configurations. The kit supports scalable system architectures by enabling point-to-point connections between compatible Keysight measurement modules and the 34980A mainframe infrastructure.
– Compatibility & Integration
This connector kit integrates directly with the Keysight 34980A Mainframe ecosystem. Full compatibility is confirmed with eight module types spanning the 349XX series, making it suitable for data acquisition, multiplexing, and signal routing applications within that platform. Solder cup design provides field-proven reliability for permanent installations and custom system builds.
