Source Meter Takes On 3D Sensing Challenges

Tektronix introduces the Keithley Model 2606B System SourceMeter instrument that packs four 20W SMU channels into a single 1U form factor chassis. Targeting the 3D sensing manufacturing industry, the unit combines the capabilities of a precision power supply, true current source, 6½-digit DMM, arbitrary waveform generator, and pulse generator into one instrument. With its patented series ranging topology, the meter delivers up to 20,000 operations per second resulting from faster and smoother range changes and outputs that settle more quickly.


As per Tektronix, over the next few years, 3D sensing technology is expected to become commonplace across consumer devices including smartphones and widely deployed in a range of automotive and industrial applications. Laser diodes based on VCSEL (vertical-cavity surface-emitting laser) technology form the heart of 3D sensors and must be tested throughout the supply chain. Manufacturers face challenges to increase test capacity as demand grows while preserving floor space. The Model 2606B’s compact form factor means test engineers and system integrators can significantly increase per-rack channel capacity without adding more racks of test equipment.

The Model 2606B integrates the equivalent of two Model 2602B System SourceMeters to form a four-channel 1U full-rack unit. It reportedly improves density by 3x since there is no need for a thermal spacer (for airflow) between units. For example, 12 Model 2606B SMU channels can be mounted in the same 3U rack space as only four SMU channels under the previous solution.


For a smooth transition, the Model 2606B is completely code compatibility with the Model 2601B and 2602B. It uses the same Test Script Processor programming code as the existing instruments, eliminating the need for any code changes. The Keithley Model 2606B System SourceMeter SMU instrument is available now, priced from $22,600. For more details, visit Tektronix/Keithley.
