Keithley Instruments Inc. has announced its series 2600 System SourceMeter instruments for testing electronic components. Based on proprietary and patent-pending third-generation source-measure technology, the instruments combine a high-throughput source-measure unit (SMU) with a scalable form factor for integration of 1 to 16 SMU channels into systems. Two models are available: the 2601 single-channel and the 2602 dual-channel. The embedded Test Script Processor lets users program a sequence of test commands and execute high-speed automated test sequences independent of a PC. Test Script Builder software is included.
