The Tektronix TLS216 is a 500 MHz oscilloscope with 16 analog channels.

Does it really have a 2GS/s sampling rate on ALL 16 analog channels?

That's seems quite remarkable! Wonder what hardware they used in there? 16 ADC modules?

What about the bandwidth? Does that drop when you use several analog channels at the same time?

If there is no limitation, neither on the bandwidth and the sampling rate, when using all 16 analog channels at the same time, this scope seems very impressive!

So what's the catch behind this? It is real-time sampling right? And not equivalent time sampling, right?
What am I missing here then?

If you look at the overview secion of product specifications it clearly says 2-GS/s Simultaneous Sampling on All Channels and if you look at the specifications it says 16 channels, 16 samplers, 2GS/s. I guess, on its own, samplers could mean sample and hold circuits which is then interfaced to one or more ADCs but in this case it doesn't - or so it appears.

I've personally never seen that machine Before so thanks for pointing it out. Must have cost a fortune when it was introduced.....

No BNC inputs.  :scared:

I guess it's an analog logic analyzer in that sense :)

Does it contain any kind of protocol decoding?

No. It is way too old for that. Don't waste time or money on this piece of antique.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.
