FreeLists / si-list / [SI-LIST] Sin(x)/x

[Doug Smith <doug@xxxxxxxxxx>]

It's that time of month again as the keys have been clicking on the 
keyboard here. My latest article has been posted at http://emcesd.com 
on a common scope setting whose default value can hide significant 
measurement errors while troubleshooting or veriyfing circuit 
performance. The picture link to the article is located at the bottom 
of the the index page, but there are 80 articles above that on the 
same page!

Sin(x)/x, the Forgotten Setting - Part One
-------------------------------------------------------

The many features of digitizing scopes both makes them useful and at 
the same time can cause problems if they are all not set properly for 
the measurement to be made. This month's Technical Tidbit at 
http://emcesd.com covers the Sin(x)/x setting and its affect on 
measurement accuracy, which can be severe. For many measurements, the 
recommendation is to disable this feature.

I make available course notes, including updates, in pdf format to 
people who have attended my full two day High Frequency Measurements 
and Noise seminar. This month I have updated the files hfmd-ia.pdf and 
hfmd-c.pdf with significant information. If you have attended my two 
day seminar and have lost the download information, send me an email 
with your current contact information and tell me when and where you 
took the course. I will email you the download instructions for the notes.

On August 17th in Boston, MA, USA, just before the IEEE EMC Symposium, 
I will be delivering a one day EMC seminar with Michael King, 
co-presenter. This course is a combination of our material and is 
quite unique. The URL for more information is:

In the Fall, Michael King and I are presenting a 3 day public seminar 
on EMC and ESD topics. More information is at:
