Work

Since 1985 I've been working at Stanford Research Systems, where I'm currently Engineering Manager. SRS is an interesting company with a wide variety of products including Test and Measurement instrumentation, vacuum science products, atomic frequency standards, and software.

 Projects

 

  • TheSR785 Dynamic Signal Analyzer is a brand new state of the art FFT analyzer.It includes many features missing from the earlier SR780 such as frequency domain system identification, order tracking, and a time/histogram mode.
  • SR272 Data Acquisition Program is a brand new 32 bit Windows program for acquiring data from SRS's SR250 boxcar integrator system.
  • The SR780 was SRS's first 2-channel FFT analyzer and the first to include Analog Devices powerful AD21020 DSP chip.
  • The SR760 and SR770 were our first single channel FFT analyzers.
  • The SR850 is a powerful digital lock-in amplifier built on SRS's "platform" architecture.
  • The SR430 is a multichannel scaler, a somewhat obscure instrument. It was the first instrument to use our16-bit 80C186 based "platform" operating system which I originally wrote and which as since been modified to form the basis for many SRS instruments.
  • The SR640 Dual Channel Filters represent my only attempt at analog design.
  • Way back in the '80s I wrote a series of first-generation DOS data acquisition programs including the SR265, SR565, SR575, SR465, and SR626 which despite looking a bit tired are still in use by scientists all over the world.
  • The SR245 was SRS's first computer linked data acquisition product and is also still in use all over the world.
  • I also write and publish SRS's catalog every 2 years.
  • I also manage SRS's computer networks, which are based on Novell's Intranetware operating system.
  • I also designed and maintain SRS's database system, based on the powerful but somewhat obscureDataflex database system.

Interests

  • We really like Borland'sC++ Builder as a windows development environment.
  • Without C++, life as we know it would certainly cease to exist. I'm a big proponent of using C++ in embedded systems. Don't beleive anyone who tells you it's too big and slow.
  • Embedded Systems are hot right now. We were doing them before anyone even had a name for them.
  • Digital Signal Processing and Fourier techniques are at the heart of all our spectrum analyzer products.

Education

  • BSc.E. in Electrical Engineering, Princeton University, 1979
  • Ph.D. in Applied Physics, Stanford University, 1985

Dissertation: XUV Spectroscopy of Atoms and Laser Applications
