20Mhz will be hard using a prop. I'm sure that its possible though. A logic analyser running at 40Mhz (or even 80Mhz) would also be nice. BNC connectors would be nice. Then we can use all the x10 and x100 probes to measure whatever voltage we want.
I would like to see upgradable firmware. Maybe downloadable user functions? After all, this is the propeller we're talking about, infinitely flexible.
Why not put in a SD card? This could be a good place to store capture data, firmware upgrades, user functions.
I really like the idea that the scope could decypher I2C, SPI and other protocols.
Publish the firmware. This way, people could get the scope to do even more things.
Today comes populating the prototype for the analog circuitry, this is a feasibility study to make sure my design is correct before doing the schematic for the entire board (sans power circutry which will go through a similiar process as the analog).
I just stumbled across this thread while trying to find out if there's any Linux support for the USB oscilloscope as I was considering purchasing one. I know it's a little late, but here's another vote for Linux and/or Mac support. My only Windows box is for games.
Hi. I'll put in my vote: I would like to see longer cables on the probes. The specs mentioned above are probably too late to change, but the probe might not be. The best option for the probes would be something like the USB cable that came with the new Prop Education Kit: with a retractable wheel design. With a 4' probe and the reel, it will be much easier to debug the electronics while keeping the bench clean.
Hey I just got my hands on one of these for christmas and I've been trying to get it to work under WINE. Im in the process of testing it (and comparing it to a Windows XP computer running the same software). I'm not sure if it can keep up with the transport rate, but it looks promising.
So for all of the Linux users that want to use this:
Here is WINE (which will enable you to install the .exe in Linux): http://www.winehq.org/
I'd be very interested in working on a linux version of the software if anyone else would use it.
For now I'll continue playing with it in WINE and see if it holds up to running on an actual Windows computer.
What do you mean by the new one? I believe I have the new one (it was purchased less than two months ago).
Also, are you saying the specs on the USB Oscilloscope for sale dont match what someone posted on this thread? I think this is a forum for feature requests, so I don't think these features should be taken as 'specs'.
1) Bandwidth
2) Delayed trigger, as well as high AND low trigger
3) BNC probes
4) Better software!
5) Isolated power supply? << Ground loops.
I bought one of the old scopes when they first came out and have used it a LOT! Overall it's performance has been adequate for my needs, but the software isn't as good as the hardware. For example, it is difficult to see on my laptop. It's been abuse tolerant, both myself and students have made some mistakes but it hasn't broken yet.
I'll be one of the first to line up and buy a new one! Then I will be able to lend my old one to students and leave it in the lab for general use.

A delayed trigger feature would be very useful, especially if one wanted
to get better time resolution of events that were far from the trigger.
I second this one - I have a Parallax Scope, and this is the single thing I wish for most of all, even more so than increased speed & buffer size.
I thought I would check in and see what the status is on this product. I believe one of OBCs pictures from his trip showed some hardware for the device. Is it close enough to mention a release date? Need a beta tester?

I'd love to be one of·the Beta testers for the new Oscope.
I have v5.1.1
I have just put together A new PC with XP-64, I also have XP-32 on an other machine. And Vista on My laptop. I have All the tools to beta test the Oscope, I also have most of the Parallax line up. $BS2,$BSp,SX/B,Prop. just to mention a few.

How many of these were you able to include in the prototype?
* very low cost, clever virtual design made from few parts
weighing almost nothing
* minimum 10Mhz bandwidth
* very simple to operate, not too many features, a simple version
* available in kit or assembled
* student/operating/assembly/tutorial/experiment book, based
on the Basic Stamp series and sections with servos and
Penguin/Boebot etc. robots in mind
* self calibrating (feeds in a reference square wave and adjusts it
initially to fit the scale)
* appealing traditional display in high resolution where the virtual
knobs and controls look absolutely real

So for all of the Linux users that want to use this:
Here is WINE (which will enable you to install the .exe in Linux): http://www.winehq.org/
Here is an explaination on how to set up the COM port: http://www.linuxforums.org/forum/wine/84154-can-someone-help-me-understand-how-wine-sees-com-ports.html
I'm not sure the COM Port works well.
I'd be very interested in working on a linux version of the software if anyone else would use it.
For now I'll continue playing with it in WINE and see if it holds up to running on an actual Windows computer.

I would vote for an XY presentation mode, and open source software (with no expectation of additional support for the software from Parallax)
Cheers!
