Keithley debuts software upgrade and switch/multimeter options

Tag : Screw Switch

Keithley Instruments at Semicon West introduced Keithley Test Environment Interactive (KTEI) V7.1 forthe company’s Model 4200-SCS semiconductor characterizationsystem. The company also announced an expansion of its Series 3700system switch/multimeter and plug-in card family.
The KTEI software upgrade broadens the capabilities of the Model4200-CVU (capacitance-voltage unit), offering software support forcharacterizing higher power semiconductor devices at up to 200 VDC(or 400 V differential) and up to 300 mA. This capability is usefulfor engineers working with laterally diffused MOS (LDMOS) and otherhigher power semiconductor devices in automotive, display, MEMS,and other high-power applications. KTEI V7.1 also adds softwaresupport for other new functions, including differential DC bias andquasistatic C-V testing. It offers an expanded set of device testlibraries as well as a variety of software enhancements designed tospeed and simplify testing.
The company also announced an expansion of its Series 3700 systemswitch/multimeter and plug-in card family with the addition of twonew plug-in cards, the Model 3724 dual 1X30 solid state FET relaymultiplexer card and the Model 3750 multifunction I/O card.

The Model 3724 dual 1X30 FET multiplexer card features scanningspeeds 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 offsetcurrent of less than 10 nA. The solid-state relays can beautomatically configured into either a dual 1x30 or 1x60multiplexer. The card also features temperature-measurementcapability with automatic CJC sensors when used with the optionalscrew terminal accessory.
The Model 3750 multifunction I/O Card features 40 digital I/Ochannels with high-current driver outputs that can sink up to 300mA, allowing them to drive relays directly without any interfacecircuitry. The Model 3750 also features two programmable analogoutputs offering both voltage- and current-programmable isolatedanalog outputs including 0 to 20 mA, 4 to 20 mA, or +/-12 VDC. Italso comes with four totalizers/counters with 32-bit resolution andis gated with a 1-MHz input rate.
Prices: Model 3724, $1595; Model 3750, $1250.
