Well... TEMPEST as I heard of it, means only intelligible information (none to
be found). The device can interfere such that nothing else works, but as long
as nothing intelligible can be found in that noise, then it's TEMPEST. The
TEMPEST guys can set me straight on this.
As for ITE products, I
In a company not really far away and only years ago, I was evaluating a
computer with a (then new) CD drive. I discovered there was no bypassing on
the headset line ("What for?. it's only audio!") and was able to show our

monitored back in the 1960's because electric typewriters created distinctive

Those of us who have TEMPEST experience knows this is nothing new. I saw a
demonstration back in the 80’s where display images were reproduced from
radiated emissions given off by a monitor 10 meters away. This really freaked
out the US government and prompted a lot of TEMPEST PC and peripheral

this was common knowledge among security guys, but he introduced the
phenomenon to the public.

Derek:
"
There are very few PS2 keyboards made and sold these days. Most keyboard data
goes over a USB or wireless connection. There is a link to an October 2008
article that includes snooping on USB keyboards by looking at the radiated
emissions.
I do like the description as a “Hotel attack” if only
Around 1980 a guest professor demonstrated that technique using radiated
emissions. The receiving equipment fit into a large briefcase.

Hello Ian,
UL makes their full library of wire styles available on-line through their
“UL iQ” system. It requires a free registration. For those already
registered with UL’s “MyHome” system, you can access the iQ databases

The first part, requesting "Trace Average" is easy. It's the average of 100
traces, in whatever amplitude you are using. If you were to take the average
of two traces, displayed in units of dBm, and saw -32 dBm on the first trace
and -40 dBm on the second trace, then the Trace Average woul

For UL wire style information, go to the UL web site, WWW.UL.com, and go to
the UL iQ pages. This page has several different data bases that you can
access, one of which covers AWM wiring materials and wire styles. You'll first
need to register, then log-in.
