The Keysight 16048G is a 1-meter port extension cable that bridges Keysight impedance analyzers to devices under test via a 4-terminal pair configuration. It extends measurement ports from the instrument’s terminals to the DUT and accepts user-fabricated test fixtures through its BNC male connector board. The cable supports DC bias voltage application, enabling comprehensive impedance characterization across a wide frequency range.

– Compatibility & Integration
The 16048G connects directly to Keysight E4990A and Agilent/HP 4294A impedance analyzers. For the E4990A, select "4TP 1M" in the adapter setup menu before measurement. Adapter setup using a 100 Ω reference resistor for phase compensation is recommended prior to testing.
