3-Slot HV Low-Noise Triaxial Cable Instructions

Description

The Keithley Instruments TRX-1100V-X is a 3-slot high-voltage, l ow-noise triaxial cable. Examples of how you
can use this cable are applications that characterize and test high-voltage, low-leakage devices, m aterials, and
modules, such as silicon carbide (SiC), gallium nitride (GaN), power MOSFETs, transient suppression devices,
circuit protection devices, power modules, and bat teries where high-voltage sourcing and low-current
measurements are required.

This cable is commonly used with the Keithley Instruments Model 2470 High Voltage SourceMeter
