Hi Are we talking about a 2ns 5345 or a 53181? They are vastly different devices. The counter you asked about originally is approximately 10X better than the one in the article you reference.

Your'e right about the price (I paid 200 for my 53181A plus another 150 for the ovenized oscillator option) but there is a lot more to be had here. Id say that for most people it would be about following the story. There is a lot to learn about what makes these guys tick that is fun. Lets start with the HP Journal from June of 1974 on the web just a click away. Price is zero money. http://www.hparchive.com/Journals/HPJ-1974-06.pdf I think that most people are past the issue of what can be done in the basement. If you have a problem then somebody else has been there before you and then you learn something. I started working with complex chip layout and design (processors /FPGAs) in 1990 and later on mentoring others as to how assemble prototypes not long after. It is my belief that when you propose to use a new part that you are also thinking about how you are going to assemble it to test the circuit Go to youtube there are several videos of how to fancy complex stuff. A lot of people use pizza ovens. Have a look at the website for Scottys Spectrum Analyzer. Much of what is done here was unthinkable in the basement 10 years ago. http://www.scottyspectrumanalyzer.com/ Regards; Greg On 3/25/2011 8:38 AM, Bob Camp wrote: > Hi > > The whole counter thing has been run around in a thread back a month to > three months ago.
