Keithley Instruments, Cleveland, OH 1990-2004
Staff Software Engineer 2000-2004
Senior Design Engineer 1996-2000
Design Engineer 1990-1996
Designed embedded firmware for multiple instrument products used for sensitive electrical measurements. Position tasks increased from primarily front panel and user interface to assuming responsibility for all or the majority of product design. Interacted closely with marketing and applications development and manual writer’s group. Programming primarily done in C with some assembler for Motorola 68K (68302, 68306, 68332) and Coldfire (5407) families. Development tools include Green Hills MULTI, Orion, and X-Ray debuggers as well as Altera FPGA design tools.
All software engineers at Keithley received coursework in embedded C++ for future applications.
Instrumental in designing the following products:
2001 DMM menu scheme with over 600 unique menu items. Front panel menu firmware was used for all two-line display products for 14 years. Received technical achievement award.
Designed firmware for 2002 and 2010 DMM and 7001 and 7002 switch systems
Designed 68331-based platform for 2300 series power supplies and 7999-6 microwave switch system
Sole firmware engineer for 2182 Nanovoltmeter. Designed and implemented a “delta mode” operation to make measurements more immune to temperature change and reduced thermal noise.
Implemented design for Model 6220 and 6221 current sources which allow two instruments to communicate without going through a computer.
Led firmware design for 2700 Scanning DMM. Same platform was then used in 2750 five-slot scanning DMM, 2701 Ethernet version and 2790 airbag tester. Received two awards for the 2700 including a Technical Achievement Award.
Designed and implemented firmware for temperature sensor linearization, including RTDs, thermocouples, and thermistors. Converted obsolete RTD calibrations to ITS-90 specifications
