2600B Series SMU
Keithley’s Series 2600B System SMU instruments are the industry standard current-voltage source and measure solution for highly automated production test applications. Both dual- and single-channel models tightly integrate a precision power supply, true current source, DMM, and electronic load with pulse generating capabilities. Plus, TSP® technology runs complete test programs for automated system applications, and TSP-Link® technology enables daisy-chaining up to 64 channels for high volume parallel test.

SMU 2600B Series SourceMeter
Complete production test without sacrificing footprint

Meet all your production test needs with two completely isolated channels of wide dynamic source and measure within the same footprint. Each 40 W channel provides 6½-digit precision resolution source and measure from 10 A pulse to 0.1 fA and 200 V to 100 nV at less than 100 µs pulse width and within 0.1% of settled value.
Simplifying FET Testing with 2600B
Highlights
- Up to 2 channels in the same footprint
- Widest dynamic range of voltage and current
- Highly accurate 100 µs pulse expanding DC production test capabilities
Embedded scripting for unmatched production throughput

Test Script Processor (TSP®) technology embeds and executes complete test programs inside the SMU instrument to deliver industry-best performance.
