I'm looking for an a very basic oscilliscope that I can hook up to my Kenwood 7300 tuner. Any suggestions? Thanks in advance.
Follow Ups:
the shipping, actually. What, I believe, you're asking for is one that you can connect up to the H and V outputs to monitor multipath, right? If that's the case, there's little need for any of the bandwidth that's the usual specification you'll see in the ads.I'm sure you've spent some time at eBay surfing around. On the assumption that you'll only use it with the tuner, then just get one of the most basic and low bandwidth scopes (10Mhz is about as low as you'll find unless its *really* old).
The biggest problem is that many of the older 70s vintage scopes may need to restoration attention and may well have burn marks on the scope face. Without your seeing them first, this will always be a risk.
Lastly, their weight usually means that they'll cost more to ship than they're worth. I'd suggest you attend a local ham radio swap meet and you'll find some locally to bargain with - and you'll be able to confirm they're working ok first.
Hope that helps.
Cheers,
David
I'm planning on buying locally so shipping won't be an issue. The info you gave me is great. Indeed, all I want it for is the 'cool factor' of seeing the waveform. Thanks for pointing me in the direction of the low bandwidth scopes. Question: Should I assume that these low bandwidth oscilloscopes have the right inputs to hook into the V and H Multipath outputs on the tuner? Also what kind of cable would I use. Sorry to sound so ignorant!Thanks again
The scope should have a horizontal and vertical input - usually BNC connectors - on it.Almost all scope from the past 35 years will have a timebase generator that handles the sweep for horizontal. This will have to be diabled/switched out so that the vertical component from the tuner can be used. Most of these scope will have this capability hence the need for a manual unless you're comfortable enough with scopes functionality already to just figure it out.
At the frequencies you'll be dealing with, most any coaxial cable will do just fine - this isn't where rocket science kicks in. Its not something to worry about.
Cheers,
I found this site with a bunch of older oscilloscopes. If you get a chance, would you tell me which one you think would be good with my Kenwood 7300 rceiverhttp://www.electronixandmore.com/misc/oscilloscopes.html
thanks in advance
