| Munich--November
12, 1996--Teradyne, Inc. today introduced a new
high-accuracy, intelligent, DSP-based analog measurement
system called PRISM (PRecision Integrated Signal Measurement)
for its Z1800-Series and Spectrum 8800-Series families
of circuit-board testers. Demonstrated for the first
time at the Electronica trade show held here, the PRISM
analog module delivers state-of-the-art precision, throughput,
stability, and measurement flexibility.
The new PRISM analog instrument offers the following
features:
- DSP-based rather than op amp-based for maximum flexibility
and throughput
- Industry-leading precision, especially at the extremes
of measurement ranges
- Excellent stability with temperature and humidity
variation
- High throughput with an average of 250 analog tests
per second
High performance (16 bit A/D)
- Flexibility for powerful function test and mixed-signal
testing using other instruments and the VXI-Vector
Processor (VP)
- R, C, L, RC, RL, diode, transistor b tests standard
- Bridge mode for small capacitor, RC tests
- High-speed Hi-Cap test using DSP stabilization techniques
- On-board temperature-stabilized reference with a
simple, one-year calibration cycle
- Test capacitors in parallel with the device-under-test
to speed analog debug
- High power resistors available for fast capacitor
discharge up to 55V
- Specified at the fixture interface: 15-35 degrees
Celsius, ? 80% humidity non-condensing
The PRISM VXI analog module is standard on the Spectrum
8800-Series testers and will ship with all systems.
All Z1800-Series test systems can be configured with
the PRISM-Z module as a complement to the current Z1800-Series
analog instrument. This add-on option will be available
in early 1997.
Teradyne is the world's leading supplier of automatic
test equipment. Headquartered in Boston, the company
also manufactures telephone-equipment test systems and
backplane equipment. The Assembly Test Division, Walnut
Creek, California, manufactures circuit-board test systems
for the commercial board-test market.
