'[EE] Logic scope? Digital oscilloscope?'
While looking around for a digital oscilloscope, I found a Tektronix TLS 216
Logic Scope on eBay. By the looks of it, it's a 16 channel digital
oscilloscope (not unlike the TDS 1000/2000 series?) combined with the
capabilities of a logic analyzer. It's on the very-high-end of my budget but
I wouldn't mind spending so much if it will serve me well and last for some
A few questions:
Is this unsuitable for a serious electronics student/hobbyist?
Could it be used as an oscilloscope? Is it a viable replacement?
Would I be better off with a regular 2/4 channel scope?
If so, would a new scope be better than a used scope in the same price
range? (ie. TDS 1002 vs. TDS 224)
I'm also looking at a Tektronix TDS 224 (4 channel) on eBay -- I have read
good things about the 200 series in general so that would definitely be my
second choice. Any ideas on what I can expect to pay for this?
I'd really like to make the right decision when spending this much but I
find it hard to research specific oscilloscope models as most search queries
are flooded with test equipment resellers' pages and generic descriptions. I
am open to any suggestions.

takes up way too much precious workbench space and I can't capture the
waveforms without photographing it)

I think the TLS216 is very good, but the active probes are expensive to
replace, when and if they need it. And I believe there are two channels
that act as oscilloscopes and they are limited in input voltage. But I
can't say this for sure because it's been a while since I've used one.
In my opinion, you'd be better served with the TDS224. It's smaller,
light weight, very portable (about the size of a lunchbox), and as scopes
go, relative inexpensive. I use several of the TDS200 series nearly
every day, and I wouldn't know what to do without them.
Bottom line from my perspective is don't sepnd the money on the TLS216.
Get the TDS224 instead. I think you'll be happy, and won't regret it.
Hope this helps you out.
