2601B-PULSE System SourceMeter® 10 ps Pulser/SMU InstrumentDatasheet through highly automated pulsed l-V production test. For automated system applications, the 2601 B-PULSE's Test Script Processor (TSP®) runs complete test programs from inside the instrument for industry-best throughput. In larger, multi-channel applications, the Keithley TSP-Link® technology works together with TSP technology to enable high-speed, pulser/SMU-per-pin parallel testing. Because the 2601B-PULSE offers full isolation that does not require a mainframe, it can be easily reconfigured and re-deployed as your test applications evolve. The new 2601B-PULSE System SourceMeter 10 |us Pulser/SMU Instrument with PulseMeter™ technology is an industry-leading high current/high speed pulser with measure plus the full functionality of a traditional SMU. This new pulser offers leading 10 A current pulse output at 10 V with a pulse width minimum of 10 |us, perfect for testing vertical cavity surface emitting lasers (VCSEL) used in LIDAR and facial recognition, LEDs for lighting and displays, semiconductor device characterization, surge protection testing, and so much more. The pulser's built-in dual 1 Megasample/second (MS/s), 18-bit digitizers make it possible to acquire both pulse current and voltage waveforms simultaneously without the need to use a separate instrument. The 2601B-PULSE is a powerful solution that significantly boosts productivity in applications ranging from benchtop characterization Key Features • Industry leading 10 A @ 10 V, 10 microsecond pulse output • No tuning required; works with inductive loads up to 3 pH • Dual 1 Megasample/second digitizers for high speed I/V pulse measurements (pulser function only) • DC capability up to ±40 V @ ±1.0 A, 40 Watt • TSP technology embeds complete test programs inside the instrument for best-in-class system-level throughput • TSP-Link expansion technology for multi-channel parallel test without a mainframe • USB 2.0, LXI Core, GPIB, RS-232, and digital I/O interfaces • Supported in the Keithley KickStart non-programming software tool SMU (I or V Source) Full DC Operation Pulse Operation: Pulse Width >150 ps, typical Dual Integrating ADCs: One each for V and I Solid-state switch routes either SMU or Pulser to output terminals Safety Interlock Input PULSER (I Source only) DC Bias Pulse Operation: 10 ps < Pulse Width < 500 ps Dual 1 MS/s High-speed ADCs: One each for V and I External Interlock/Connector box included with 2601B-PULSE

Pulsed Testing for Device Characterization Testing real device operation and minimizing the heating effects with on-wafer testing just got easier with the 2601B-PULSE SMU. Thermal management is critical during the testing of many devices, especially those at the semiconductor wafer level, such as VCSELs, laser diodes, and LEDs. Pulsed I-V testing minimizes the heating effects of the current in the device, especially if tested at the wafer level when devices have no temperature control circuitry. Testing with DC would either change their characteristics, or at worst, destroy them. Later on,...

2601B-PULSE System SourceMeter 10 µs Pulser/SMU Instrument Unmatched Throughput for Automated Test with TSP Technology For test applications that demand the highest levels of automation and throughput, the 2601B-PULSE’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 the timeconsuming bus communications to and from the PC controller, and thus dramatically improves overall test times. • Conditional...

SMU-Per-Pin Parallel Testing with TSP-Link Technology TSP-Link is a channel expansion bus that enables multiple 2601B-PULSE SMUs to be inter-connected and function as a single, tightly-synchronized, multi-channel system. The 2601B-PULSE’s TSP-Link technology works together with its TSP technology to enable high-speed, SMU-perpin parallel testing. Unlike other high-speed solutions, such as large ATE systems, the 2601B-PULSE 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...
