I think you are just overstating this issue (...)

In my case seeing single pulses at +100 MHz clock (actually I don't remember the exact frequency) was not a problem to be solved with a simple logic scope, LED signalization or other very low frequency solution.
You know ... there are problems that need proper instruments to be solved.

Hi again,

Yes I agree, and that is why I reported needing a scope for measuring and decoding the IR signals from the IR remotes I wanted to know the protocols for. I was able to make a truly "universal" remote with that information. It was also interesting to see the many different protocols currently in use in different types of remotes.

For most of the remotes a low-cost $30 ARM based single channel scope worked ok.

I also used a pin diode for the IR sensor as it was faster than the other photosensitive devices I tried. I think a glass diode might work too because they act like fast photocells when light shines on them in a certain direction.

Although I did say you can do a lot without a scope, you can do more with one, as long as you don't mind learning how to use one and also what it is you are looking at when you connect it to a circuit.
Currently I do not do electronic measurements as much as I did years ago, but I would not want to give up my scopes.

 

I dont have no problems my logic tool can catch 100 mhz no problem on 4 channels
