Hello All

We are looking for 2 Field trial customers in the UK for our first
product.
It is a 50MSS digital storage oscilloscope(DSO) which connects to a PC
or laptop.

Ideally you have a real need and use for such an instrument and would
see it as
a valuable tool for your professional or hobby activity.


What we need:
We need 2 field trial customers in the UK. They must have a
requirenment
for an instrument of this type. They have to fill in a short(3-4 pages
of multiple choice questions) field trial questionnare.


What you get:
2 channel DSO with external trigger input. 50MSS
Software applications create Oscilloscope, Multimeter and Spectrum
Analyzer
Instruments.


How to apply:
E-mail me at the address given.
State why you would need such an instrument and what you would use it
for.


E-mail applicants will receive further details.

Regards and thanks

Denis

P.S. Unfortunatly the current trial is only open to UK residents.

What's the realtime bandwith?

Hello all

Any PC or Laptop running Win 98, Win ME, 2000 or XP will do.
No Linux support yet.

The computer needs to have a parallel port available.

If you're interested email me and Ill forward all information.

Thanks for your interest.

Denis

Can't be more than 25 MHz. Fred Nyquist sez so.

If you could create brickwall, linear phase anti-aliasing filters, then
perhaps. Sadly in the real world, causality reigns supreme. The realtime
bandwidth is supposedly sampling rate/10 for TEK scopes, so the above might
be only 5MHz realtime bandwidth. Remember that the 3DB point isn't the same
as the Nyquist frequency where signals must be attenuated completely to
avoid aliasing and filters with steep cut-off points but with linear phase
are difficult to realize.

That would be true for a single shot or non repetitive signal,
but for a repetitive signal it's quite possible to reconstuct in software a
much higher
frequency provided the sampling gate is narrow enough,
and sufficient traces are combined.
The sampling times must be dithered on each trace relative to the trigger to
achieve this.

Concur entirely. My point was that with that sampling rate, it's not much
of an oscilloscope.

My experience is that all digital scope systems employ a/d that are fast

but too grainy so that the input dynamic range is inadequate compared to
a relatively low cost analog scope.
DC coupled differential measurement is carried out in the processing so
that 12bits is still all you get.
