The Keysight M9186A is a PXI-based, isolated, dual-range voltage/current source module for automated test equipment (ATE) applications. This two-slot module delivers independent amplifier stages for low and high voltage ranges, enabling precise sourcing and measurement in automotive electronics and general electronic test environments. The integrated safety interlock protects DUTs during high-voltage operation, while 4-quadrant capability in the low range supports bidirectional sourcing.
Technical Specifications
Dual-Range Amplifier Architecture
• Low Range: ±16V at maximum 200mA
• High Range: −10V to 100V at maximum 20mA
• 4-Quadrant Operation: Low range supports ±200mA over ±16V
• DC Voltage Range: −10V to 100V
Sourcing and Sensing
• Isolated voltage and current sourcing
• SENSE input enables feedback-loop voltage regulation to the device under test
• Common output connection for both amplifier ranges
– Key Features
• Safety Interlock: Automatically disables the high-voltage amplifier and opens all relays upon circuit break; front-panel LED indicates interlock status and supports external fixture limit switches
• Dual-range flexibility accommodates parametric leakage testing, bias current measurement, impedance characterization, threshold voltage verification, and clamp voltage assessment
• High-voltage range validates clamp diodes in modules driving inductive loads
– Typical Applications
• Automotive electronics parametric testing
• I/O pin leakage and threshold voltage measurement
• Impedance and clamp voltage characterization
• Clamp diode verification in inductive load circuits
– Compatibility & Integration
The M9186A installs in PXI-compliant cPCI, PXI-1, or PXI Hybrid slots within standard PXI chassis. Compatible with PXI or PXIe remote and embedded controllers. Software drivers include IVI-COM, IVI-C, and LabVIEW G, supporting LabVIEW, LabWindows/CVI, Microsoft C/C++, C#, and VB.NET development environments.
