Data-Acquisition System Has 40 Channels And 5-kHz Throughput
The CR5000 measurement and control system features 40 channels, 5-kHz throughput, and an on-board instruction set. This standalone, battery-powered data-acquisition system can operate between −25°C and 50°C standard, and between −40°C and 85°C extended. Able to measure nearly every commercially available sensor, it can be used with most wireless and hardwire communications options, such as Ethernet.

It includes a battery-backed real-time clock, battery-backed SRAM memory, a graphical display, a PC memory card slot, an optically isolated RS232 interface, a 9-pin port, and a 7-Ahr lead-acid battery. System operation from internal or external 12 V dc is allowed by its minimal power requirements. Program generation, data collection, and real-time and historical graphical data display is provided through Windows-based software.

Windows-Based Cable Test Program Has Build And Browser Abilities
TestRite software, designed for Series 90 PC-based continuity analyzers, now features Build and Browser display capabilities. The Build feature lets users build assemblies and quickly verify assembly point locations in the Windows operating environment for simpler and faster setups. Build display functions that aren't available on competitive software are provided by the Browser capabilities. With these, users can virtually display any files that a browser can access, such as GIFs, JPEGs, and HTML.

Designers can use TestRite 2.2 to learn, program, and operate the company's continuity analyzers and cable testers. Its TestRite (Editor) mode targets programming, testing, and assembly guidance. Also, it adds tester-related command buttons to the Windows toolbar. The TestPanel mode, meanwhile, is used for production assembly and test. It displays a graphically simulated tester front panel that includes selection "buttons" on the monitor.

TestRite software for Series 90 systems costs $495. The microprocessor-based tester version is $295. Both come with a user's manual.

80-MHz Waveform Generator Provides Stable, Accurate Output
The 33250A generates standard waveforms from sine and square to ramp and sawtooth for circuit testing, design verification, and waveform simulation. This 80-MHz device features direct-digital-synthesis techniques that let users create a stable, accurate output on all waveforms down to 1-µHz frequency resolution. Custom arbitrary waveforms can be generated with a 200-Msample/s rate, 12 bits of vertical resolution, and a waveform memory depth of 64,000 points. It also comes with "built-in" sweep, burst, modulation, and external clock reference.

The generator's user-friendly front panel permits easy adjustments. Its high-resolution color graphical display concurrently presents multiple parameters for rapid waveform modifications. A TCXO timebase supplies a 1-ppm/year frequency accuracy rate for demanding applications. New users will benefit from the 33250A's built-in help system. Also, the standard GPIB and RS-232 interfaces come with full programmability. Available now, the 33250A costs $4250.

Probe Pair Comes With A 1400-V Peak Differential Voltage Range
Two active differential probes, the ADP300 and ADP305, feature a 1400-V peak differential voltage range. Designed for EN61010 Category III (1000 V rms) probing, they can be used on appliances and portable equipment, as well as in fixed-installation environments. They also provide 80-dB CMRR at 50/60 Hz and low-circuit loading. The ProBus interface lets them become an integral part of the acquisition system. They're controlled through the oscilloscope's front panel or via remote commands. Additionally, designers can save these settings as a "front panel file" that can be used to recreate a measurement setup.

The ADP300's 20-MHz bandwidth suits it for troubleshooting low-frequency power circuits and other signals where the voltage reference is elevated from ground. Its sensitivity ranges from 1 to 350 V/div. The ADP305 boasts 100-MHz bandwidth and a larger set of probing accessories. Appropriate for probing high-speed power electronics, it can acquire signals from 200 mV/div to 350 V/div.

With a six-week delivery time, the ADP300 costs $450, and the ADP305 costs $950.
