1989年，3458诞生，过去21年啦，hp/agilent没能再取得突破，一憾。
Multimeter Calibration 
Scott D. Stever 
Scott Stever was project manager for the HP 3458A Multimeter. He has written for the HP Journal before;in the February 1 985 issue he reported on his work on the dc and ohms measurement sections for the HP 3457A Multimeter. He also is the coinventor of a patented automatic attenuator compensator for this instrument. He joined HP in 1 979, after graduating from the Georgia Institute of Technology with a BSEE degree. Analog circuit design has become his main professional interest. Scott was born in Corpus Christi, Texas, is married, and has a six year-old son. He lives in Loveland, Colorado. When he is networking on or flying his airplane, he likes to ski and play tennis. 
Wayne C. Goeke 
Design of the analog-todigital converter for the HP 3458A Multimeter was Wayne Goeke's main responsibility. As a specialist in analog circuit design, he has contributed to the development of a number of instruments, including the HP 3497A Data Acquisition/Control Unit, the HP 3468A Digital Multimeter, and the HP 3478A Multimeter. Two pending patents on the HP 3458A are based on his ideas.Wayne studied at the University of Wisconsin at Madison, where he received both his BSEE (1977) and his MSEE (1979) degrees. He was born in Freeport, Illinois, is married, and lives in Fort Collins, Colorado. In his spare time, he is active in his church and enjoys volleyball, skiing, and back packing.
 Stephen B. Venzke
Since Steve Venzke joined H P i n 1 9 6 5 , he has been associated with a wide range of products, including theHP 3455A Digital Voltmeter, the HP 3585A Spectrum Analyzer, and the HP 3577A Network Analyzer.He designed the input amplifier, ohms converter,current shunts, and autocalibration circuits for the HP 3458A Multimeter and has now become a production engineer for the product. He is the originator of two patents, one for a low-frequency current divider for function generators, the other for an analog-to-digital converter technique. Steve received his BSEE degree from the University of Minnesota (1965), and his MSEE degree from Colorado State University (1 968). Born in Minneapolis,Minnesota, he is married and has two daughters.He lives in Loveland, Colorado, where he teaches eighth-grade Sunday school as an avocation. He is also interested in audio equipment and enjoys backpacking and fishing.
Ronald L. Swerlein
The design of the ac front end, the digital ac algorithms, the transformer,and the power supplies were Ron Swerlein's major contributions to the development of the HP 3458A Multimeter. His analog circuitry was also used in earlier instruments, like the HP 3468A Digital Multimeter and the HP 3478A and HP 3457A Multimeters. He is named inventor in a patent describing ac autocalibration circuits, and he has published two papers about digital ac measurement. His bachelor's degree in engineering physics (1978) and his MSEE degree (1979) arefrom Ohio State University. Ron was born in Toledo,Ohio, is married, and lives in Longmont, Colorado.He spends his leisure time reading science fiction. 
 High-Throughput Design
 Gary A. Ceely
Shortly after graduating from Virginia Polytechnic University with a BSEE degree in 1979,Gary Cee|y joined HP's Loveland Instrument Division. His development projects have included firmware design t h e HP 3456A Systems DVM, the HP 3488A Switch/Control Unit, the HP 3852A Acquisition/Control Unit, and the HP 3054A Data Acquisition System.During development of the HP 3458A Multimeter,Gary's responsibilities included the ERS, firmware architecture, operating system interface, and language parsing. Born in Alexandria, Virginia, he lives in Loveland, Colorado. His favorite leisure activities are skiing, waterskiing, kayaking, volleyball, tennis, and aerobics. 
David J. Rustici 
The measurement and calibration firmware of the HP 3458A Multimeter were David Rustici's focal responsibilities at HP's Loveland Instrument Division.He is now a firmware manager. Originally, he had joined the Civil Engineering Division in 1976, after graduating from the University of Wisconsin at Madison with a BSEE degree His responsibilities there included the HP 3808A and HP 3850A Distance Meters. His work on the latter resulted in a patent, and another patent for the HP 3458 is pending. David is the coauthor of a paper describingfirmware for an intelligent digital voltmeter. He was bom in Racine, Wisconsin, is married, and has a son and a daughter He lives in Loveland, Colorado. In his off-hours, he enjoys skiing, bicycling,golf, and travel. 
Oavid A. Czenkusch 
As R&D engineer in the voltmeter laboratory of the Loveland Instrument Division, Dave Czenkusch has been involved in a number of voltmeter and multimeter developments, including the HP 3458A, and a digital voltmeter for the HP 3235 SwitchATest Unit. One of his ideas for the HP 3458A resulted in a patent application. Dave's BSEE degree is from Purdue University (1 983). He joined HP the year of his graduation and developed a professional interest in digital design and firmware. He was born in Speedway,Indiana, is single, and lives in Loveland, Colorado.He enjoys skiing in the winter and looking forward to the skiing season and bowling in the summer. |
