I'm considering purchasing an oscilloscope, and have no idea what to do.
Intended Use:
I'm constructing a ham radio transceiver kit for the 80m and 40m bands (3.5-4.0, and 7.0-7.3 Mhz). I want to use the scope for trouble-shooting and alignment of the radio. I will probably construct a linear amplifier to be used at the same frequencies. Might also try a 20m radio (14.0 Mhz)
Intended User:
No experience with a scope. I've decided that I should probably avoid buying used, as I don't want to spend my time trying to determine if the problem is the circuit or the scope. Also, I want to work on radios, not repair scopes.
What I Think I Know:
The scope market has moved primarily to digital. My research, indicates that the key digital specifications are sample rate, memory, and resolution. From what I've read, radio (analog signals) will require high resolution if you want an accurate representation of the signal. Unfortunately, scopes with 12, 14, or 16 bit resolution are high dollar. This is leading me to believe that for my intended use, analog may be the way to go. Either way, I think that 100Mhz would be adequate.
The Questions:
Should I buy analog or digital?
What are the minimum specifications that I will need for the intended use?
If digital, what combination of sample rate, memory, and resolution do I need?
I really have no idea what I'm doing. It's difficult enough just trying to understand the radio theory, let alone trying to become a scope expert. I hope there is someone experienced with my intended use, that can suggest the appropriate scope and specifications.
Thanks,
John
