Superior Bench-top SMU Measurement Performance Source and measurement resolution - 10 fA and 100 nV The B2900B Series SMU consists of four models — the differentiation is between the number of channels, and measurement and sourcing resolution. The B2901B (single-channel) and B2902B (dualchannel) SMUs have 100 fA and 100 nV measurement resolution, 1 pA, and 1 µV sourcing resolution. The B2911B (single-channel) and B2912B (dual-channel) SMUs have 10 fA and 100 nV both measurement and sourcing resolution. The B2900BL Series SMU consists of two models. The B2901BL SMU has 1 pA and 100 nV...

Capture transient phenomena effortlessly The B2900B/BL Series SMUs support a high-speed sampling measurement function that permits the capture and display of low-frequency transient phenomena. The B2901BL and B2910BL SMUs support a 200 µs (5,000 points/second) and 50 µs (20,000 points/second) sampling rate. The B2901B and B2902B SMUs support a 20 µs (50,000 points/second) sampling rate, and the B2911B and B2912B SMUs support a 10 µs (100,000 points/second) sampling rate. The maximum achievable sampling rate depends on many factors, including signal level, ambient noise, and desired...

4-wire measurement capability permits accurate low resistance measurement When measuring small resistances the innate cable resistance can create serious measurement error. To solve this, the B2900B/BL Series SMU supports a 4-wire (also known as a remote sense or Kelvin connection) measurement function. In the 4-wire scheme two of the connectors force current and the other two connectors measure voltage. Since the connectors measuring voltage do not have any current flowing through them, they can accurately sense the actual voltage at the DUT. Measure large capacitive loads without...

SCPI commands provide compatibility and versatility Standard Commands for Programmable Instruments (SCPI) are a popular and easy-to-understand instrument control protocol. The B2900B/BL Series SMU supports two SCPI command sets, conventional and default, to provide both code compatibility and flexibility. The conventional command set has a large number of its commands compatible with those of older SMUs (such as the Keithley 2400) to minimize code conversion work. The default command set supports advanced B2900B/BL Series SMU features and they should be used to fully utilize its performance...

Feedback mechanism stabilizes voltage and current sourcing Since SMUs have the ability to very accurately measure their own current and voltage output, they have many advantages over conventional power supplies. All SMUs have internal feedback loops that provide instantaneous feedback to the sourcing circuitry, which in-turn allows the SMU output to remain accurate and stable even if the load conditions change unexpectedly. Limit (compliance) feature prevents device damage SMUs also possess a voltage and current limit (compliance) feature that allows the user to set limits and to protect...
