Keithley debuts software upgrade and switch/multimeter options
-- Test & Measurement World, 7/17/2008 7:19:00 AM
Keithley Instruments at Semicon West introduced Keithley Test Environment Interactive (KTEI) V7.1 for the company’s Model 4200-SCS semiconductor characterization system. The company also announced an expansion of its Series 3700 system switch/multimeter and plug-in card family.
The KTEI software upgrade broadens the capabilities of the Model 4200-CVU (capacitance-voltage unit), offering software support for characterizing higher power semiconductor devices at up to 200 VDC (or 400 V differential) and up to 300 mA. This capability is useful for engineers working with laterally diffused MOS (LDMOS) and other higher power semiconductor devices in automotive, display, MEMS, and other high-power applications. KTEI V7.1 also adds software support for other new functions, including differential DC bias and quasistatic C-V testing. It offers an expanded set of device test libraries as well as a variety of software enhancements designed to speed and simplify testing.
The company also announced an expansion of its Series 3700 system switch/multimeter and plug-in card family with the addition of two new plug-in cards, the Model 3724 dual 1X30 solid state FET relay multiplexer card and the Model 3750 multifunction I/O card.
The Model 3724 dual 1X30 FET multiplexer card features scanning speeds of greater than 1000 channels/second, including measurement, and switch-only scan rates of greater than 1,200 channels/second. The card also offers 200-V, 0.1-A switch/carry capacity with offset current of less than 10 nA. The solid-state relays can be automatically configured into either a dual 1x30 or 1x60 multiplexer. The card also features temperature-measurement capability with automatic CJC sensors when used with the optional screw terminal accessory.
The Model 3750 multifunction I/O Card features 40 digital I/O channels with high-current driver outputs that can sink up to 300 mA, allowing them to drive relays directly without any interface circuitry. The Model 3750 also features two programmable analog outputs offering both voltage- and current-programmable isolated analog outputs including 0 to 20 mA, 4 to 20 mA, or +/-12 VDC. It also comes with four totalizers/counters with 32-bit resolution and is gated with a 1-MHz input rate.
Prices: Model 3724, $1595; Model 3750, $1250.
