Power Supplies for the Stimulus Response System

IN DESIGNING POWER SUPPLIES for the 8180A Data Generator, 8181A Extender, and 8182A Data Analyzer, the most important objectives were high load current capability and serviceability within a restricted space. The sizes of the instrument cabinets were limited by the desire to produce a system suitable for benchtop operation. To accommodate the generator, the analyzer, and perhaps two extenders on a bench, the cabinet dimensions obviously had to be limited. The card rack in the generator holds...

New Multi Frequency LCZ Meters Offer Higher Speed Impedance Measurements

These instruments, combined with an optional interface and a component handler, make production-line measurements of the impedance parameters of discrete electronic components rapidly and accurately at actual operating frequencies. by Tomio Wakasugi, Takeshi Kyo, and Toshio Tamamura MANY INSTRUMENTS used for production-line impedance measurements have onJy one or two test frequencies, usually 1 kHz and.'or 1 MHz. But electronic components, once installed in a piece of equipment, must operate at...

Parametric Characterization of Digital Circuits

The representative timing parameters of synchronous ICs are setup time, hold time, and propagation delays. During the setup and hold times, data has to be stable before or after an active clock transition occurs. The propagation delay is the time between stimulation and the output reaction of a device. This value depends upon the complexity of the circuit and its technology, and varies from less than 1 nsfor an ECL gate to over 100 ns for an MOS gate. Hence, the measuring instrument must have...

Power Self Test

LOCAL PROGRAMMING of the 8182A Data Analyzer is done by means of front-panel softkeys. As selections are made, the functions of the softkeys change and are displayed on the CRT. The programming concept provides eight pages of information, four pages for programming instrument parameters, three for displaying the results of a measurement, and an eighth page for use as an alphanumeric display to aid the operator a of computer-controlled system. For remote programming, the 8182A is provided with...
