Programmable Parametric Tester for Discrete Semiconductors (IST-8800)

• Tests MOS-FETs, TRIACs, SCRs, Diodes, Transistors, Regulators, Zeners, and J-FETs
  
• Performs parametric measurements or Go/No Go tests on over 40 device parameters
  
• Built-in relay matrix offers accurate and versatile measurements from the nano amp range up to 1,200V
  
• Battery back-up RAM stores user written test routines for "one-time set-up" operation
  
• Automatically detects any open, short, or malfunctioning junction of the DUT prior to applying power
  
• IEEE-488, High Voltage, and Automatic Handler Interface ports
  
• Self calibrating software

The IST-8800 is a fully programmable, low cost tester that provides parameter measurements or parametric GO/NO GO test for transistors, diodes, MOS-FETs, Regulators, Triacs, Zeners, SCRs, and J-FETs. These devices can be tested up to 5 amps or 1200 volts with a measurement range down to the nano amp range. Only four universal test fixtures are required which can test the device across a wide range of packages.

The user-friendly resident software simplifies the operation and programming of the 8800 while the "Quick Set" function provides a means for running fast one-time-test setups. User written routines can be stored in the battery back-up memory for future use. The 8800 is a "Stand Alone" instrument so no additional software, hardware, or special training is required to operate the unit.

The 8800 uses a relay matrix to connect the required test circuits, select the voltage/current sources and establish the needed mesaurement loops. With the auto polarity capability, it identifies the device type (NPS or PNP, P-ch or N-ch) and applies the appropriate circuits to the DUT automatically. The following parameters can be tested:

• TRANSISTOR: Icbo, Iceo, Iebo, BVcbo, BVebo, BVceo, Bce(sat, Vbe(sat), hFE, Icer, Ices, Icev, BVcer, BVces, BVcev
  
• DIODE: Ir, BVr, Vf
  
• ZENER DIODE: BVZ, IZR, VZR, VZF
  
• J-FET: Idss, Igss, BVgss, gm
  
• SCR &TRIAC: +/- Igt, +/- Vgt, Ih
  
• VOLTAGE REGULATOR: +/- Vo, +/- Iib, delta V
  
• MOS-FET: Idss, Igss, BVdss, Vgs(th)
