How can a 150 MHz Tektronix TDS420 oscilloscope, with a spec of 100
MS/s, say that it's sampling at 10.0 GS/s?

In the last photo at the URL below, the display indicates that the
sample rate is "10.0 GS/s". How can that be?

I am selling this scope on Ebay. But it wasn't my personal scope and
I'm not very familiar with Tek's "newer" digitizing scopes. Is it
using some sort of averaging, to achieve a higher apparent sample
rate, or what?

... advertising junk snipped for convenience...




Well Tom,

that'S funny advertising you do for your ebay sales.

Do you still wonder why there is no answer from "the anti-spam robot"?
No pearls to be thrown into the pig's mouth.




Okay, we will shade light to this: 10 GS/s means equivalent sample
rate. See the Tektronix references for papers on "sequential" and
random sampling. All can be found in Tektronix very cute paper: "ABC
of oscilloscopes". Online downloadable on Tektronix website.

Did you mean "XYZs of Oscilloscopes"? There is also an "ABCs of
Probes...", there.

Andreas,

Assume, for a moment, that it WAS "advertising".

What do you have against advertising?

And then, also, why the personal insult?

I am quite familiar with the "...casting pearls before swine"
concepts. It is rather dismaying to see that used, in this context.

Let's see, then. Do you think that "profits" and "capitalism" and "the
rich" are... "bad"?

Curious.

Tom Gootee
