The Tektronix A1005 Diode Adapter enables precise testing and characterization of axial lead diodes and semiconductor devices with compatible Tektronix curve tracers. This adapter integrates into curve tracer test fixtures, providing Kelvin sensing capability for accurate low-resistance measurements while minimizing lead and contact resistance effects.
Technical Specifications
• Maximum Voltage: 2000V
• Kelvin Sensing: Supported
• Input Terminal: 5k ohm input terminal for output voltage offset with opposite polarity input at one-tenth desired output voltage
• External Load Resistance Connection: Parallels with internal 50k ohm resistor when LOAD RESISTANCE switch set to EXT position
• Pin Jacks: Allows patching of additional components into test circuits
– Key Features
• Kelvin sensing configuration eliminates lead and contact resistance from low-impedance measurements
• Programmable output biasing through dedicated 5k ohm input terminal
• External load resistance capability for flexible device characterization
• Patch panel integration for modular test circuit configuration
• Integrated safety enclosure through compatible test fixture design
– Typical Applications
• Axial lead diode I-V curve tracing and parametric analysis
• Semiconductor device forward and reverse bias characterization
• Low-resistance component testing requiring four-wire (Kelvin) measurement technique
• Device biasing studies using programmable offset voltage
– Compatibility & Integration
The A1005 works with Tektronix 370 Series, 5CT1N, 7CT1N, 575, 576, 577, 370, 371, and 371A curve tracers. Compatible test fixtures accommodate A1001 through A1005 adapters, 3-pin adapters without Kelvin sensing, and A1023/A1024 surface mount adapters. Connection employs patch cords between patch panel and adapter panel on the test fixture.
