Keithley 2612 Dual-Channel System SourceMeter: The Parallelized Power for Precision I-V Characterization
In the research, development, and production line testing of semiconductor devices, nanomaterials, and advanced components, high-precision dual-channel sourcing and measurement capabilities are becoming increasingly crucial. The Keithley (now part of Keysight Technologies) 2612 Dual-Channel System SourceMeter integrates two high-performance precision power supplies, current sources, digital multimeters, and electronic loads into a single compact chassis. It delivers an efficient, integrated solution for applications requiring synchronous stimulus and measurement of two-terminal devices.
To ensure the long-term stability and inter-channel consistency of such high-precision, multi-channel instruments, professional calibration and maintenance support are critical. The Shenzhen Bao'an District Shajing Fangfengrui Instrument Equipment Business Department possesses specialized expertise in the field of precision Source Measure Unit (SMU) services and can provide 2612 users with comprehensive technical support and service assurance.
The 2612: A Precision Platform for Dual-Channel Synchronous Measurement
Core Performance and Technical Features:
Dual Independent High-Precision Sources and Measurement:
Each channel provides a voltage range from 100 nV to 40 V and a current range from 10 fA to 2 A (models 2612A/B), covering testing needs from weak signals to medium-power levels.
Each channel features 6½-digit resolution for voltage and current measurement, ensuring high-precision data acquisition.
The two channels can operate completely independently or be connected internally in series or parallel to extend voltage or current ranges.
Four-Quadrant Operation and Pulsed Mode:
Each channel supports true four-quadrant operation, capable of both sourcing and sinking power to accurately simulate various operating states of two-terminal devices in real circuits.
An optional pulse mode provides pulse widths as low as 50 µs, avoiding measurement errors introduced by self-heating effects when testing power or thermally sensitive devices.
Powerful System Integration and Automation:
Built-in TSP® (Test Script Processor) technology allows users to store and execute complete test scripts within the instrument, enabling standalone operation and ultra-high test throughput.
The TSP-Link® expansion bus facilitates easy synchronization of multiple 2612 units or other TSP-enabled instruments to build parallel test systems with more channels (e.g., a four-channel 2614 system).
Standard interfaces include LAN and USB, with an optional GPIB interface.
Typical Application Scenarios:
Synchronous Two-Port Device Testing: Synchronous I-V characterization of devices such as Bipolar Junction Transistors (BJTs), optocouplers, and small relays.
Differential and Transmission Line Testing: Analysis of differential signals or transmission line characteristics using dual-channel sourcing and measurement.
Multi-Site Parallel Testing: In production testing, leveraging the dual-channel independence and TSP technology to perform parallel testing on two independent devices under test (DUTs), significantly increasing throughput.
Comparative Studies of Materials and Devices: Simultaneously measuring two similar or different samples for direct performance comparison.
Professional Calibration Ensures Channel Accuracy and Consistency
For dual-channel SourceMeters, calibration must not only ensure the voltage/current sourcing and measurement accuracy of each individual channel but also the relative accuracy and synchronization between the two channels, which is crucial for differential measurements and precise comparisons.
The Shenzhen Bao'an District Shajing Fangfengrui Instrument Equipment Business Department can provide critical support to users in this area:
Dual-Channel Independent Accuracy Calibration: Precision calibration and traceability for all ranges of the voltage source/meter and current source/meter of each channel.
Inter-Channel Matching and Synchronization Calibration: Calibrating the output consistency, measurement consistency, and the synchronization accuracy of triggers and sweeps for both channels under identical settings.
Pulse and Four-Quadrant Characteristic Verification: Verifying the parameter accuracy of pulse outputs and the boundary performance of four-quadrant operation.
TSP-Link Multi-Instrument System Verification: Evaluating the overall synchronization accuracy and performance of systems expanded with multiple 2612 units via TSP-Link.
Fault Diagnosis and Repair: Professional diagnosis and repair of issues such as single-channel failure, excessive inter-channel deviation, communication faults, and TSP script execution errors.
Conclusion
The Keithley 2612 Dual-Channel System SourceMeter, with its innovative dual-channel integrated design, exceptional measurement accuracy, and powerful TSP automation capabilities, provides an efficient solution for applications requiring synchronous or parallel I-V testing. It integrates two complete high-performance SMUs in a single unit, offering unparalleled test flexibility while saving rack space and cost.
Ensuring the long-term precision and coordinated operation of this powerful parallel testing engine requires in-depth expertise specific to multi-channel systems. By partnering with a specialized service provider like the Shenzhen Bao'an District Shajing Fangfengrui Instrument Equipment Business Department, users can ensure that their 2612 systems—and any expanded systems—consistently maintain optimal metrological and performance states.
