Measurement Automation: How to Save Screens of 86100C DCA-J, SDA830 and E4440A/E4445A to Local PC Through GPIB

Picture from agilent.com
Measurement automation can save you a lot of pain in many cases on top of the advantages of higher productivity and greater accuracy in case of performing repeated day-to-day test and measurement tasks. Several examples using simple GPIB commands to capture screen pictures from different instruments to a local PC are given in this article with the complete workable VEE codes shown how to implement. They are easily portable with any programming languages such as Matlab and C or scripts like Perl and Python. If you are interested in how to:

  • Save screen image from Agilent DCA-J 86100C to local PC as GIF files.
  • Save screen image from LeCroy SDA830ZI-A to local PC as PNG files.
  • Save screen image from Agilent E4440A/E4445A spectrum analyzer to local PC as GIF files.
  • Dump raw spectrum data from Agilent E4440A/E4445A spectrum analyzer to local PC as text files.
  • Dump raw phase noise log plot data from Agilent E4440A/E4445A spectrum analyzer to local PC as text files.

Finally, 50G Hz electrical BW with 32Gbps hardware CDR module is available for DCA from Agilent


    I have been looking for high bandwidth, high fidelity CDR modules for high speed (25Gbps and beyond) SerDes characterizations and finally it's here! It is Agilent 86108B Precision Waveform Analyzer which claimed to have "industry best intrinsic jitter below 50 femtoseconds, channel bandwiths to 50GHz, and clock recovery to 32Gbps ...."

If you are interested to know more, "Tips and Techniques for Accurate Characterization of 28Gb/s " is one of their good application notes to start with.

Real-time Oscilloscope Spectrum Analyzer and Matlab


This article is trying to understand a typical clock-like signal measured and interpreted in different domains(time domain and frequency domain) and try to correlate the different results produced from different sources such as measurements, analytical math equations or Matlab functions bridged by Discrete Fourier Transforms(DFT).

Digital storage oscilloscope‎‎(DSO)‎‎ fundamentals



This article has some equations and I didn't find a proper way of editing them using the blog build-in editor. And after I finished the article in google documents to take advantage of its equation editor function, I failed to find a proper way of publishing it to this blogger. I end up setting up a google website and published the article there through importing....
