[sdiy] Logic Analyzer Advice

[Terry Bowman]

I need to repair some old frequency counters and whatnot. It sounds like a job for a logic analyzer but I've never actually used one.  What would be wonderful is the ability to put a clip on the counter DIP, tell it what chip it is and then watch it count away in hexadecimal. Someone told me that this is "decoding" the data which makes sense. Anything that doesn't require me to do any mental gymnastics is ESSENTIAL. I'm not rich but I'll pay for what I need. Anything less is a waste of time.

What would be best for this? I'm sure there are factors that I'm not even aware of. PC based is an option as I'm going to put a 32" monitor on my bench. I have a line on a beautiful old HP DSO that's a dream to use and has one built in but there's no "decoding".

The counters in question have Nixie tubes in them. Some go down to 1Hz so they're not bad for fooling around with trans-AF. I have an LED model that I'll practice on first.
