The Keithley 4200-TRX-0.3 is a triaxial cable assembly engineered for low-noise signal transmission in precision semiconductor and materials characterization. At 0.3 meters in length, this cable connects the 4200-PA Preamplifier to devices under test or to FORCE/SENSE terminals on 4200-SCS and 4200A-SCS Parameter Analyzers. Standard 3-slot male triaxial connectors terminate both ends.
## Technical Specifications
• **Cable Type:** Triaxial
• **Length:** 0.3 meters (1 foot)
• **Connectors:** 3-slot male triaxial on each end
• **Frequency Range:** 0 Hz to 4 GHz
• **Electrical Impedance:** 50 Ω

## Key Features
• Triaxial construction preserves signal integrity across low-frequency DC and RF measurements up to 4 GHz
• 50 Ω impedance matching minimizes reflections and noise
• Short 0.3-meter length supports preamplifier placement near the device under test, reducing noise pick-up from extended cable runs
• Designed specifically for the 4200-SCS and 4200A-SCS ecosystems
## Typical Applications
• Semiconductor device characterization
• Material characterization and process qualification
• Low-level DC measurements requiring high signal fidelity
• Capacitance-Voltage (C-V) measurements
