Technical content

The Series 2600B System SourceMeter SMU Instruments are the industry’s leading current/voltage source and measure solutions, and are built from Keithley’s third generation SMU technology. The Series 2600B offers single- and dual-channel models that combine the capabilities of a precision power supply, true current source, 6½-digit DMM, arbitrary waveform generator, pulse generator, and electronic load – all into one tightly integrated instrument. The result is a powerful solution that significantly boosts productivity in applications ranging from bench-top I-V characterization through highly automated production test. Built-in web browser based software enables I-V testing through any computer from anywhere in the world. Or, use your Android smart device to perform plug & play I-V testing with fingertip control with the Keithley IVy application. For automated system applications, the Series 2600B’s Test Script Processor (TSP®) runs complete test programs from inside the instrument for industry-best throughput. In larger, multi-channel applications, Keithley’s TSP-Link® Technology works together with TSP Technology to enable high-speed, SMU-per-pin parallel testing. Because Series 2600B SourceMeter SMU Instruments have fully isolated channels that do not require a mainframe, they can be easily reconfigured and re-deployed as your test applications evolve.

A Tektronix Company

TEK.COM device under test (DUT), and share the measurement results with others. It allows you to visualize, interact with, and share measurement results without programming, while gaining a deeper understanding of your DUT. These unique capabilities boost productivity across a wide range of applications in R&D, education, QA/FA, and more. Unmatched Throughput for Automated Test with TSP Technology For test applications that demand the highest levels of automation and throughput, the 2600B’s TSP technology delivers industry-best performance. TSP technology goes far beyond traditional test command sequencers — it fully embeds then executes complete test programs from within the SMU instrument itself. This virtually eliminates all the time-consuming bus communications to and from the PC controller, and thus dramatically improves overall test times.

• Conditional branching
• Advanced calculations and flow control
• Variables
• Pass/Fail test
• Prober/Handler control
• Datalogging/ Formatting Test Script DUT TSP technology executes complete test programs from the 2600B’s non-volatile memory. SMU-Per-Pin Parallel Testing with TSP-Link Technology TSP-Link is a channel expansion bus that enables multiple Series 2600B’s to be inter-connected and function as a single, tightly-synchronized, multi-channel system. The 2600B’s TSP-Link Technology works together with its TSP technology to enable high-speed, SMU-per-pin parallel testing. Unlike other high-speed solutions such as large ATE systems, the 2600B achieves parallel test performance without the cost or burden of a mainframe. The TSP-Link based system also enables superior flexibility, allowing for quick and easy system re-configuration as test requirements change. SMU1 <500ns SMU2 SMU3 SMU4 All channels in the TSP-Link system are synch ronized to under 500ns.

2400 Software Emulation

The Series 2600B is compatible with test code developed for Keithley’s 2400 SourceMeter SMU instrument. This enables an easier upgrade from 2400-based test systems to Series 2600B, and can improve test speeds by as much as 80%. In addition, it provides a migration path from SCPI programming to Keithley’s TSP technology, which when implemented can improve test times even more. For complete support of legacy test systems, the 2400’s Source-Memory- List test sequencer is also fully supported in this mode. Test 1 running To Device 1 GPIB, USB, or Ethernet TSP-Link Test 2 running To Device 2 Test 3 running To Device 3 SMU-Per-Pin Parallel Testing using TSP and TSP-Link improves test throughput and lowers the cost of test.

TEK.COM 2600B System SourceMeter ® SMU Instruments Third-generation SMU Instrument Design Ensures Faster Test Times Based on the proven architecture of earlier Series 2600 instruments, the Series 2600B’s SMU instrument design enhances test speed in several ways. For example, while earlier designs used a parallel current ranging topology, the Series 2600B uses a patented series ranging topology, which provides faster and smoother range changes and outputs that settle more quickly. The Series 2600B SMU instrument design supports two modes of operation for use with a variety of loads. In normal mode, the SMU instrument provides high bandwidth performance for maximum throughput. In high capacitance (high-C) mode, the SMU instrument uses a slower bandwidth to provide robust performance with higher capacitive loads. Simplify Semiconductor Component Test, Verification, and Analysis The optional ACS Basic Edition software maximizes the productivity of customers who perform packaged part characterization during development, quality verification, or failure analysis. Key features include:
