Tektronix 370B Programmable Curve Tracer
370B and 371B Programmable Curve Tracers
Tektronix curve tracers offer power and versatility to test the DC characteristics of semiconductor devices. The 370B and 371Bcurve tracers combine a simple to use front panel, digital acquisition and display,and programmability to serve a variety of application needs.In the R&D lab, Tektronix curve tracers are used for characterization of new designs, extraction of SPICE parameters,failure analysis and data sheet generation.In manufacturing test, Tektronix curve tracers are used to verify device quality and process monitoring. They are also used for incoming inspection to verify device performance, perform failure analysis and match components.

The World Standard for High-resolution Curve Tracers
The 370B, the world standard for high-resolution curve tracers, provides up to20 A/2,000 V sourcing capability combined with 1 pA and 50 μV measurement resolution. The 370B performs DC parametric characterization of integrated circuits, transistors, thyristors, diodes, SCRs, MOSFETs, Electro-optic components, solar cells, solid-state relays and other semiconductor devices. It has push button source and measurement configuration so it’s easy to change from one test to the next.
The Industry Leader in High-power Curve Tracers
The 371B, the industry leader in high-power curve tracers, performs DC parametric characterization on a wide variety of power semiconductors including thyristors, SCRs, IGBTs and power MOSFETs. The high-voltage collector mode permits testing the Off-characteristics of a device up to 3,000 volts. The pulsed high-current collector mode provides output current pulses greater than 400 amps peak to test On-characteristics and permits high-power testing up to 3,000 watts. In the sweep measurement mode, the 371B automatically constructs a family of curves while stimulating the device with low duty cycle pulses. With this capability, power curves can be displayed without excessive heating of the device.
Interactive Programmable Control
Interactive control of all 370B and 371B measurements is accomplished from the full-featured front panel or over the GPIB. Every operating parameter can be controlled using the GPIB controller. 370B and 371B Series LabView drivers are available at the Tektronix.com web site. These drivers have many of the building blocks to create a custom measurement solution.
Store and Recall Setups and Digitized Curves
Up to 80 digitized characteristic curves can be stored on a diskette or in internal non-volatile memory and recalled at the touch of a button. A live curve can then be compared with a previously stored curve to assess temperature drift or other changes in operating parameters. To help identify the data, up to 24 characters of text may be used to label or annotate the curve data. Operating parameters can be adjusted, stored and recalled using several storage methods including the 370B and 371B system memory, the built-in 1.44 MB floppy drive, or sent externally via the GPIB controller.
Automated Cursor
The 370B and 371B provide three cursor measurement modes. The dot cursor provides direct screen readout of voltage, current, gm or DC beta at any point. The window cursor can be positioned between two curves to measure small signal beta or gm and can also be used for visual go/no-go tests. The function line cursor provides screen readout of a slope or intercept value.
Sweep measurement Mode
In the sweep measurement mode, the curve tracer automatically constructs a family of curves. The 371B achieves this with low duty-cycle pulses. With this capability, power curves can be displayed without excessive heating of the device.
Direct Hard copy Printouts
Curve output data can be sent directly from the 370B and 371B to a Citizen iDP-3240 thermal printer. Printing can continue while the 370B and 371B perform the next tasks.
