And what is the bloody point of a sampling oscilloscope ? They are only useful on repetitive signals and you can look at eye diagrams ...
They are useless for day to day work , debugging work , signal analysis (analog or digital).
I'm still wondering where I can order this oscilloscope and where I can find some kind of datasheet.
The only alternative is an old Tek monster that cost a few K$ on the second hand market with spare parts getting difficult to find ....

If you can live with analog sampling, then an even older Tektronix monster can be had for $100s and they include full service documentation. A couple of them even include random sampling so a delay line or pretrigger is not required to show the trigger edge.

David,
I suppose that you mean the Tek 7000 series ....
I check it, the frames are not expensive but the head and the other dedicated plugin you need are still very expensive.
The 7000 frame is huge, I have no place on my bench to put is unit.
Maybe you mean another type of analog sampling scope?

At $700 the price is bit steep. I recall seeing a price around $300. I think I'd rather get a Tektronix TDS820 (6GHz) from a good year.
I got a recent TDS820 and was very disappointed when I start extensive testing.
It was one of the lasted (I sold it), trigger stopped at 1,7Ghz, according specification it was suppose to be at 2Ghz, a little sad for a 6Ghz instrument.
In the beginning it was frustrating because lack of a decent documentation and it is not really like an usual scope, you have sometimes to use a DC blocker, a delay line (just very good coax cable), a power splitter and a prescaler to measure frequency above 4 Ghz and very good cables and connectors.
The trigger-to-sample-delay is generated by a ring oscillator (the majority of the delay comes from a long pcb trace)

So you just have some sort of monostable multivibrator with one end of the line at it's input and the other at it's output?
How is it affected by temperature? (External and internal as it heats itself up in the first few cycles after it's triggered.) What's the drift after a couple 10s of ns?

So, can i pay without any worry about money if i not recieve working device? due to paypal protection system?

Is it possible to get contact via paypal system?
Yes, i really need scope with BW > 4Ghz to measure rise/fall time for periodical pulses with 50-100ps edges.
