2606B System SourceMeter®
SMU Instrument
Datasheet
The 2606B System SourceMeter Source Measure Unit
(SMU) Instrument offers four 20-watt SMU channels
in a 1U high form factor chassis. Built from Keithley’s
third generation SMU technology, the 2606B offers
the combined capabilities of a precision power supply,
true current source, 6½-digit DMM, arbitrary waveform
generator, and pulse generator—all into one tightly-
integrated instrument. The result is a powerful solution that
significantly boosts productivity for demanding automated
qualification and production testing for optoelectronic
devices such as VCSELs/laser diodes used in 3D sensing,
telecommunication, and LEDs used in consumer products
and automobiles, as well as integrated devices like analog
ICs, ASICs, and system-on-a-chip (SOC) devices. When
a high SMU channel count is required, multiple 2606B
units can be stacked on top of each other without the
need for thermal spacing between units. Built-in web
browser-based software enables communicating to
the 2606B through any computer from anywhere in the
world. For automated system applications, the 2606B’s
Test Script Processor (TSP®) technology 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. Each 2606B SMU is code compatible with the
industry leading Keithley 2602B System SourceMeter
SMU Instrument when you are using the new ranges.
