Sure, here's the free program. When you're ready, buy the logic
analyzer and stop wasting time with bush league amateur stuff.

Sometimes the bush league amateur stuff is all that is needed !

Thanks for the link.

Sound card !

Get real...


I mean you can download a free logic analyzer program

That could be useful in some circumstances....any suggestions as to
good ones (that don't use serial ports as it has to run on a modern
notebook) ?

It should not be impossible to get a 100$ FPGA board, generate a VGA display,
use a 100MHz flash DC and have 100MHz logic analiser / digital storage scope
for little more then that plus the price of the probe and a few discrete
components.
Like for example he

100MSPS != 100MHz

I am looking for a free oscilloscope program for the PC to run under
Windows XP. Does anyone have any preferences ? It needs to be
quasi-real....not just a toy, but it can be very simple. I have no
need for spectrum analysis and single trace would suffice, but I do
need a calibrated timebase, for example. So far what I have found does
not meet my needs (time axis won't run slow enough, uncalibrated
timebase, doesn't quite work properly on my computer....etc.).

Take a look at:

http://www.cleverscope.com/download/

They claim to have sound card support, so it might be worth a look.

Thanks for the link - by sheer co-incidence I was also looking for something
like that, and it looks like a good one too.

With respect to "what can you measure", do some searching on mixing RF
signals down to baseband, for example, to look at 9 MHz crystal filter
performance. There have been numerous threads on Yahoo groups lately
on that, so you should be able to find some info.

Hmmm..now you have me thinking about what can be done with this "bush
league" test equipment and a downconverter....I'm thinking perhaps
two-tone intermodulation tests on RF amplifers....Cleverscope does have
a spectrum analyzer....

Visual Analyser is free. Uses your soundcard as a scope, spectrum
analyzer, audio signal generator, voltmeter etc. Scope has zoom,
trigger, calibrate, screen capture and more.

OK
But good enough for me.

Yes...that one looks pretty good for my needs too. Thanks.
