New 300 MHz PC-Based Scopes

May 1, 1994 -- PC Instruments continues to increase the bandwidth of
PC-based instrumentation with the introduction of two 300 MHz oscilloscope
cards. The PCI-425 and PCI-436 combine the features and performance of
portable oscilloscopes with the convenience of the personal computer. The
single channel PCI-425 and the dual channel PCI-435 occupy one PC/AT
expansion slot and provide:

* 300 MHz Bandwidth,
* 50 Ohm Inputs,
* 500 ps/div Minimum Timebase Setting, and
* 200 Gigasample/second Equivalent Sampling Rate.

The PCI-425 and PCI-435 also provide seven voltage ranges, AC/DC coupling,
DC offset and a probe compensation signal. Also included are 27 timebase
settings from 500 ps/div to 200 ms/div, and an automatic trigger level
algorithm to quickly establish a valid trigger level.

The 300 MHz bandwidth, combined with the 50 Ohm inputs, make these new
scopes ideal for ATE systems that need to test communications signals,
component pulse responses, and high speed digital signals. BenchCom
software is included with every oscilloscope card and provides test
engineers and systems integrators the tools necessary to integrate the
PCI-425 and PCI-435 scopes into their test environment. Also available is
the optional BenchTop software. BenchTop provides a "point-and-click"
graphics user interface with the ability to store and recall waveforms,
store and recall test set-ups, and automate test routines.

Reliability has been built-in to every PC Instruments scope. External
ground planes shield the scope from noise and provide a safe path for
static dissipation. The high performance of the scope is accomplished
without incorporating any adjustments or relays, therefore eliminating two
major sources of reliability problems. And, if a scope board should
develop a problem, the company will ship a free loaner in one day.

Test, production, and manufacturing engineers who are responsible for
collecting data on components, sub-systems, and complete products will
find that PC Instruments scopes out-perform data acquisition cards and
have the features engineers need to make their measurements. And, when
compared to a portable digital oscilloscope connected to a PC, the PC
Instruments scope board costs less, takes up less bench space, and does
not require an interface board (e.g. IEEE-488), interface cable, or
interface software.

The PCI-425 sells for $1695 and the PCI-435 sells for $2695. BenchTop
software costs $495. Availability is 6 weeks after receipt of order. For
