Spectrum analyzer
A quick search of your user name reveals that it is an amateur radio call sign belonging to a New Yorker who has worked on a spectrum analyzer project with Murray WA2PZO, another call sign. Further Google search helps me get past the Forbidden notice stopping me from getting anything at all from the www.science-workshop.com website. On Google Docs, the tutorial shows up as [http://docs.google.com/viewer?a=v&q=cache:RBcioSntOhkJ:www.science-workshop.com/tutorial.pdf+http://science-workshop.com/tutorial.pdf&hl=en&gl=us&pid=bl&srcid=ADGEESjadN8byOsqwmIldZ93P02e8fI4r4Vknt61Lvm8wjYWAQ1zbcb9ELO9vZ84m-UdoHxiy5JtgUsq8__HgMgrtP9-c8YkMC5_-yyT56N-vvRSMo4NjoegpKp8FrbWYwvFGVrd8lcY&sig=AHIEtbT7vsSk72lGCNmO1jiYfltiwE5HWA RF Vision.

To be useful here, that link should acknowledge its authors' real names, and it should show its sources via footnotes. The authors should be known as experts in their fields. Otherwise, it is not a reliable source, per the guideline at Reliable sources. I am looking forward to your contribution to the Spectrum analyzer article itself more than any renewed attempt to place that tutorial in the external links.
