Summer is no time to stop learning! Register for our next NO MYTHS ALLOWED webinar!   "Link Analysis with Return Path Discontinuities" is scheduled for JULY 7, 1 pm eastern time.   In this webinar, we will explore the impact of return path gaps and via transitions on high speed serial signals using VNA measurements, 3D full wave simulations, behavioral models and circuit simulations, comparing predicted and measured eye patterns from FPGA drivers. This webinar will be sponsored by Altera Corporation,  Mentor Graphics, and CST - THANK YOU!  There is NO CHARGE for this webinar, but you need to register to attend no later than 12 noon Eastern on July 6.   Non-Intel employees may now attend our Intel classes in Hillsboro, Oregon.  All Paid Subscribers to beTheSignal.com may attend 2-day classes at Intel (Hillsboro only) for only $1,000, and Non-Subscribers for $1,500.  This significant savings will apply to the Essential Principles (EPSI) as well as our new Advanced Signal Integrity Design (ASID) classes being taught in August, 2009.  A great opportunity for those living in the Pacific Northwest! Word is just now getting out about Eric's new book, "Signal and Power Integrity - Simplified".  It will be released in August, 2009, but you can pre-order your copy NOW from Prentice Hall.     Check this out!    Did you miss the last webinar, "S-Parameters, Signal Integrity and You"?  If you have a Paid Subscription, you can still view it at  SI Content -> Video Classes. If you're a Member, you can get the webinar slides at "S-Parameters, Signal Integrity, and You"   What I Learned This Month Be sure to check out my blog to read about the new insights I’ve gained and the new technologies I've heard about from my many colleagues that help solve signal integrity problems. This blog is a forum for me to share some of my new insights collected each month, and a chance for all my fellow signal integrity engineers out there in cyber space to share your questions and insights with me at doctorisin@bethesignal.com. Setting the Standard in SI Training Bogatin Enterprises specializes in making complex signal integrity topics easy to understand while strengthening engineering intuition. Our materials illustrate how rules of thumb, approximations, and commercially available simulation tools can be used to quickly and efficiently solve signal integrity problems. We leverage TDR and VNA instruments with analysis tools to demonstrate how to fully characterize and 'hack' into interconnects to identify their limitations and optimize performance. For 20 years, Bogatin Enterprises has been setting the standard in signal integrity training.
