The Agilent/Keysight 41501-60003 is an SMU and Pulse Generator Expansion Unit that extends the measurement capabilities of 4155 and 4156 series parametric analyzers. This rear-panel expansion module automatically integrates with compatible host instruments, with additional resources appearing as native channels on the instrument’s Channel Definition page. The unit supports configurable Source Measure Units (SMUs), Pulse Generator Units (PGUs), and Ground Units (GNDUs) to match specific test requirements across semiconductor characterization, memory device validation, and materials analysis.
Technical Specifications
• Compatibility: Agilent/Keysight 4155A, 4155B, 4155C, 4156A, 4156B, 4156C
• Source Measure Unit (HPSMU option): ±200 V, up to 1 A sourcing/sinking
• Pulse Generator Units (PGUs): Compatible with 16440A SMU/PGU selector for endurance testing
• Integration: Rear-panel connection with automatic resource recognition at instrument boot-up
– Key Features
• Configurable module options pairing GNDUs with PGUs, HPSMUs, or MPSMUs
• Automatic resource detection eliminates manual channel mapping
• Native-level functionality within host instrument software and display
• Support for Write/Erase endurance cycling on non-volatile memory devices via 16440A integration
– Typical Applications
• DC leakage current and I-V characteristic measurement in semiconductor device development
• Quasi-static C-V characterization for process and yield analysis
• Insulation resistance and leakage measurements in materials science
• Flash memory and non-volatile memory cell endurance testing
– Compatibility & Integration
The 41501-60003 connects directly to the rear panel of 4155/4156 instruments and requires no external configuration—resources are recognized and displayed identically to primary instrument channels. Available configurations include Option 402 (one GNDU, two PGUs), Option 410 (one GNDU, one HPSMU), Option 412 (one GNDU, two PGUs, one HPSMU), and Option 422 (one GNDU, two PGUs, two MPSMUs).
