Propeller O-Scope Sale Start Day

Posts: 138
I have been patiently waiting for the vaunted Prop Scope for many months. Now I am in need of a new(at least to me) O-scope, but don't want to get one because I am still waiting for the P-scope.
I would be very delighted if someone who knows could give some sort of delivery estimate to end my internal debate. The last thing I want to see is the damn thing on sale as soon as I throw down for a new one.

Cheaper than Tektronics.

You'd be better keeping your eye on Ebay and pickup up a second hand Tek with a much higher spec and lower cost than one of the cheap Chinese units if you were really serious.

lt's not particularly silly, is it?
Also if you don't mind what are these selling for and can you recommend supplier?
The first production run of 500 PropScopes are being built in our Rocklin, USA office the third week of September. They should be available a week after we finish the P&P, or on the first of October.
I've been closely involved in the purchasing and manufacturing planning and I don't see any surprises at this stage which would prevent us from launching this product.

Now I don't have to prod Hanno for a beta unit anymore.

32 channels @ 100 mhz or 16 channels @ 200 mhz , bonus: uses java so you can use any platform!

Oscilloscope
Function generator
and Logic analyzer for around $200.
has more features including I2C & SPI bus analyzers, 8 channel logic analyzer,
8 channel pattern generator and even does TDR & Spectrum analysis.
I compared the waveforms to my Tek TDS 3032C and it was very accurate. The basic
timing increment is only 5 ns though.

Yes, it has a 16ch logic analyzer and 2ch 100mhz scope
A similar unit but with 4ch 200mhz scope would be better.
I think this particular model is about 1100.00
I really can't suggest a particular supplier but just search ebay and look
for someone with really good seller ratings...and read the buyers
comments.
I use a nice little Tek scope at work, my home scope is a rather lame 50mhz 2ch.
I need something better.
They have some really expensive scopes that go way up in the Ghz range
at work, but I'm afraid to even touch them.

Initial hopes were $200, but at that time we had planned on manufacturing it offshore. Because of parts procurement issues we are now building it in Rocklin at Parallax. The cost of components and labor is significantly higher than we originally expected. The design cycle was also very long at Parallax - at least two years. My guess at this point is less than $300 - maybe $249 or $279 but we won't know for certain until we're able to roll up all of our manufacturing costs (labor, components).
Hanno won't be happy with this kind of price. I may have to eat a Proto Board for him.

I had a Yokogawa DLM2000 (one of them, 4 ch) here for evaluation. From the specs, it was a great fit to my needs. 4 analog channels or 3 analog channels + 8 digital channels. Can have only 8 digital ones, but for µC that seems enough for me.
The things I liked the most:
* two zoom windows
* 125 MW storage buffer (try to get that at Tek)
* History-buffer
* great crisp display (could even hook up a monitor to it)
It can analize serial protocols like I2C, SPI, UART, CAN ... (but these options cost money, but less than at Tek). The huge storage buffer is great. It captures a complete flash of the 32k EEPROM-write of the Prop and you still can zoom in to each bit and get the data analized. Can analize two protocols at a time and trigger on patterns in the protocols (but the trigger patterns are quite short).
Overall, it was a joy to work with. Unfortunately, I found 3 severe bugs. As soon as they have fixed them, I think I'll buy one. Downside, is, it is a completely different price range than P-Scope or any other products like these. But still it is cheaper than Tek, Agilent, LeCroy ...

Ken- no need to eat a Protoboard, I can think of much better uses for one.

Download a free trial of ViewPort- the premier visual debugger for the Propeller
Includes full debugger, simulated instruments, fuzzy logic, and OpenCV for computer vision. Now a Parallax Product!
249.00 seems like a fair price for the PropScope to me.
I suppose it comes with all of the test leads?
I will definitely get one!
Are you guys writing your own custom software for it?
If so it would be great if you open sourced the program
oh, and what language would you write the code in?
If it was open source maybe Hanno could be cajoled
into writing an app for it...his ViewPort is just great!

Having said that I decided that after I finish with the QL and QL020, what my next project is: a stand alone LA. Have you seen my post about a mono LCD ?, nice. well that will be my initial LCD till I get this 800x600 color panel working.
For the ones that think that doing an LA is difficult... you should have a look at what is inside the little Intronix BOX: a Cyclone FPGA, some transistors as level shifters... and a FT232. Maybe just knowing the protocol and adding a LCD would suffice...
I am eying a new Oszi, either Hamge, Tek MSO20xx or LeCroy. The Yokogawa is just amazing but I read elsewhere else about some bugs too... I'll have to see.

I know it would not be super super fast, but it might be a fun project and usable for many chores.
The prop's video ability would mean you would not need a PC. At least I think the prop's video
capabilities could handle the job???
@Ale
I just went and looked at your maths wiki...very nice!
I think it will be helpful to me...thanks

If you know the protocol you can develop all kinds of cool apps for it.
I can't wait. Even @ $279, I'm a buyer.

Does that byte of memory hold "A", 65, $41 or %01000001 ?
Yes it does...

The HAMEG HMOxxxx is amazing. But they completely lack any protocol analysis both on analog and digital channels. It came out this spring, and they say they will add those features. No price given. Should happen by the end of this year.
The Tek 2000 and 3000 series do have a ridiculous display.
> The Yokogawa is just amazing but I read elsewhere else about some bugs too... I'll have to see.
Do you remember where?
Nick, sorry. I don't intend to hijack the P-Scope thread. But then, I can't resist to talk about measurement instruments.

I too would prefer something small and portable. But the problem is the incredible price of bare displays. If you ever tried to get some from a source that doesn't say "Oh, we no longer carry then!".
But as a starter, P-Scope would be a nice have-to.

The source is a thread in the german forums @ mikrocontroller.net, just lookup the yokogawa word in the search functions.
A 480x272 display, 4.3" while a bit small can be used with the prop with a limited number of colors. They are readily available for some few €uro, and Rayman was offering them for some 30 us $. The prop is versatile enough so several displays could be used. As extension to the PropScope, one of these displays and an extra prop could provide on-the-go display. But what keeps you from getting a cheap Oszi for few hundred ?. It will have more of everything... but it will not be a propeller.
