Here's an interesting paper on sampling technology from Mark Kahrs
That's a great paper - the most complete history of sampling technology I've
seen. I was astonished to hear that the limit is now pushing 1THz
(1000GHz)! That is a wavelenth of 300um - in the thermal infrared.
Hats off to Mark for that paper. The test equipment part of his site on
is also worth a
visit - he's also a Tek nut. Looking at the acknowlegements, David de
Giacomo also helped out on the preparation - he's a Tek and test equipment
afficionado too, and good guy: .
Thanks for the link, Fred
