Multi channel current matrix module resistivity/leakage current testing

Product Introduction

The multi-channel current switching matrix module is a modular, high-density current control solution that supports independent control of multiple current channels (typical)8~128 channels), capable of simultaneously outputting/inhaling precise and adjustable DC current. Through an excellent matrix switch architecture, users can freely configure the current values (pA to mA level), working modes (constant current/pulse/scan), and on/off timing of each channel, suitable for parallel testing, automated production lines, and complex experimental scenarios. tallofThe precision multi-channel current switching matrix module is designed for demanding weak currents (as low as picoampere level) and medium currents (up to)A core component designed for switching signal paths (100mA). It does not measure current itself, but rather serves your needsofPrecision electrostatic meter (such as Keithley 6517B, 6430, 6485/6487) or source measurement units provide reliable, low-noise, and low thermal electromotive force (EMF) channel expansion capabilities, enabling a single expensive highofExpansion of precision instruments into efficient multi-channel automated testing systems. Whether it is material characteristic analysis in R&D laboratories or batch testing of semiconductor devices on production lines, they are ideal choices for improving testing efficiency and ensuring data consistency.
