PC oscilloscope with USB interface?

Hello people

I understand there are some devices, from National Instruments, that allow you
to use your PC as an oscilloscope. AFAIK they're in ISA or PCI cards.

I am interested in turning a portable PC into a portable 'scope. Are there any
USB or PCMCIA devices that do the same as the ISA/PCI "oscilloscope card"?

Linux drivers would be a good extra.

There are some PCMCIA data acquisition cards. With the right software, you

could essentially get most oscilloscope functions out of them.

However, such cards are costly. I think National Instruments has some, but
they
run several hundred dollars each.

Also, what bandwidth do you require for your target signal? I don't think
that any
PCMCIA data acquisition card is rated for more than 1 MHz.

There are several models of portable oscilloscope available. I think
Vellemen
might be one supplier. There are also some "oscilloscope in a box" models
that
can be controlled through a parallel port.

There are even oscilloscope with built in Ethernet ports. Such equipment
is very
high end and very expensive.

What are your requirements? Perhaps that info will help someone here point
you
in the right direction.

Hi!

I would LOVE to be able to find a PC oscillosopce with the folloiwng spec:

2 Channel XY input
Separate Z inputs for the R, G and B
Clocked persistance, by which I mean the diplay continues to draw the
bem on the screen until it receives a "CLEAR" signal, that when pulsed,
clears the display.

Any ideas?

Yours, Mark.

I don't think that either a PC oscilloscope or a standalone oscilloscope is

available with 5 or more inputs as you describe.

Any digital oscilloscope will give you a persistent display. What
bandwidth
do you require, up to 1 MHz, 10 MHz, 100 MHz, or higher?

For info on PC oscilloscopes, surf to www.gage-applied.com, and look at
their product line. Their boards run up to 10,000 or so in price, but they
don' do what you want.
