Hello everyone!
So I am currently working on a project involving classroom equipment from PASCO.
(http://www.pasco.com/prodCatalog/WA/WA-9314_microwave-optics-basic-system/#overviewTab)
What I'm working on is not exactly related to the the classroom project but closely related to the measurement of the microwave frequency and I need help measuring the approximate wavelength of these microwaves. I only need to see a difference, nothing too scientific. This kit comes with a detector with output plugs and the manual says "This output can also be used for close examination of the signal using an oscilloscope." but unfortunately that's the only time an oscilloscope was mentioned. A system like this one () would be perfect, I can buy another detector if needed and I have a 200MHz oscilloscope but I don't have the funds to buy a microwave frequency counter.
I'm not entirely sure how frequency mixers work but couldn't I use one in a system where I have my microwave signal split using a beam splitter and one of those signals will go directly to a detector then to the mixer. The other signal would go through some test material, then to the detector and finally to the mixer. The mixer would output a frequency which is the difference of the two input frequencies, and since this difference would be small we could measure it easily on my 200MHz scope.
Hope this is the right forum! If not I'm sorry :(
