Keithley SMU 2650 Series High Power SourceMeter®
Features |
Benefits |
| Highly flexible, four-quadrant voltage and current source/load coupled with precision voltage and current meters | Offers best-in-class performance with 6½-digit resolution. |
| Source or sink (2651A) up to 2,000W of pulsed power (±40V, ±50A) or up to 200W of DC power (±10V@±20A, ±20V@±10A, ±40V@±5A); easily connect two units (in series or parallel) to create solutions up to ±100A or ±80V | Supports characterization/testing of power semiconductors, HBLEDs, optical devices, solar cells, and GaN, SiC, and other compound materials and devices. Applications include semiconductor junction temperature characterization; high speed, high precision digitization; electromigration studies; and high current, high power device testing. |
| Source or sink (2657A) up to 180W of DC or pulsed power (±3000V@20mA, ±1500V@120mA) | Provides the high voltage required for power semiconductor device characterization and testing, including GaN, SiC, and other compound materials and devices, breakdown and leakage testing to 3kV, and characterization of sub-millisecond transients. |
| Built-in web browser based software | Allows for remote control through any browser, on any computer, from anywhere in the world. |
| Choice of digitizing or integrating measurement modes | Supports characterizing transient and steady-state behavior precisely, including rapidly changing thermal effects. |
| TSP (Test Script Processing) technology | Avoids communication delays between the PC controller and instrument by embedding test scripts in the instrument itself, improving test throughput dramatically. |
| TSP-Link channel expansion bus | Enables multiple 2651As and 2657As and selected Series 2600B SMU instruments to be combined to form an integrated system with up to 32 channels. |
| Python Drivers Support | Harness the power of native Python commands for controlling instruments and eliminate tedious manual parsing. At your fingertips you’ll find your favorite IDE, such as VS Code or PyCharm. Learn more. |
| Compatible with Model 8010 High Power Device Test Fixture and Model 8020 High Power Interface Panel | Provides safe and easy connections for testing high power devices at either the packaged part or wafer level. |
| Optional ACS Basic semiconductor component characterization software | Maximizes productivity when performing packaged part characterization during development, quality verification, or failure analysis. |
