K-50 Probe, ECT

Broadband 50 Ohm Coaxial Test and Measurement Probe

All dimensions in inches (mm.)

Model Number: K-50L
Replacement Probe: SPL-01L-039

Applications
The K-50 coaxial probe provides an instrumentation-quality interface for broadband R.F. measurements up to 4 GHz. With the new K-50 R.F. Circuit Design, impedance characterization measurements can be performed using it as a Network Analyzer port-extending accessory. Accurate and repeatable small signal and R.F. power (50 Watts) measurements provide consistent and repeatable results. The K-50 was developed in cooperation with a leading manufacturer of advanced communications systems and is supported by a leading instrument equipment manufacturer.

Design Advantages

The precisely-controlled physical and electrical characteristics of the K-50 make it an ideal port-extending accessory for Network Analyzers and Time Domain Reflectometers. The R.F. center conductor system is captivated for maximum reliability.
The K-50 incorporates spring probes in an open architectured format to accomodate a wide range of physical circuit topologies and to alleviate the need for special geometry contact pads on the circuit under test.
