Product Description
The 370B is a high performance, GPIB programmable digital storage curve
tracer that provides static and dynamic semiconductor device measurements. The
instrument stimulates, measures, and displays the semiconductor characteristics
of a variety of two–, three–, and four–terminal devices; including bipolar
transistors, field effect transistor, silicon controlled rectifiers, diodes, thyristors,
opto–isolators, wafers, and integrated circuits. A variety of measurements can be
performed using either grounded–emitter or grounded–base configurations.
The Collector Supply produces AC, Rectified AC, or DC voltages ranging from
0 to 200 volts. This high voltage, combined with a current sensitivity of
100pA/div, permits extended breakdown measurements on a device under
test(DUT). A step generator produces voltage or current setups of either polarity
for application to the base or emitter terminal. The step generator may also be
operated in a pulsed mode to reduce DUT power dissipation.
In addition to conventional curve tracer performance, the 370B includes the
following features:
Digital storage capability that allows a bright and stable display and cursor
merriments. The 370B has a mass storage system that consists of non–vola-
tile IC memory and a 3.5 inch floppy disk drive. UP to 64 families of
characteristic curves and front panel setups can be stored on disk. And up to
9 families of characteristic curves and front panel setups can be stored in in
internal non–volatile IC memory. The stored characteristic curves can be
recalled for additional analysis and comparison.
