It looks like there's a catch to the educational pricing. In the terms of their pricing it mentions that the educational pricing is only available if the board is required for a class. Since I haven't tried to order one I guess you might be able to get around that but I'm not sure you could buy this unless your institution is listed as requiring their hardware
Damn, didn't see that, yeah
I got mine from Microchipdirect { TDGL023 } for $219 USD. They also have the BNC adapter board { TDGL024 } for $20. Ships direct to Canada.
Any extra fees? Shipping costs for example.
Why don't you try to add one of the 13 left to your cart?

Brokerage and such varies greatly and shippers that don't maintain a company presence inside Canada can't calculate it. Often the carrier will tag on the "extras".
Hi All. I ordered from Microchip too. I am in Toronto Canada. I ordered on Monday and it arrived today!

Last year Newark Canada was selling them at U.S student pricing ($99.00), thats when I bought mine. I think its worth the money, I don't know if I would have bought it if it wasn't $99.00 bucks though. I think Newark sold there stock in a couple hours just from this forum.
I see now they don't even stock it in N.America and the price they want is over 4x what I paid last year.

I've raised a question in a separate thread; if anyone has any pointers then please post them there.
The question is whether the Waveforms software running under Linux/Wine works with the hardware. I've noted how I've got the Waveforms working in demo mode, but obviously I can't take the next step.

Thanks
It almost certainly does not work under WINE.

There's an informative post by attila in the thread

I presume even though I don't know the formula that from those two values you could calculate the frequency for -3dB attenuation.
I have heard Dave talk about -3dB being the point at which the bandwidth of an oscilloscope is determined. Are there also other lesser factors which are used to determine the bandwidth?
Digilent must have had some reason to be so apparently conservative in their claimed BW.
ISTR reading somewhere that it was felt that the target markegt (beginners) would complain if they felt they has been mislead by finding the amplitude of a 5MHz signal was too low. Personally I don't agree with that, since they will need to understand what equipment's spec does and doesn't mean.
It tends to be important to limit the d(surprise)/dt to keep their attention, so I do like that they're keeping to a novice-friendly style of specification. If we used this in our class, we'd have no problem looking up or testing the actual -3dB point on our own - in fact, it'd make a good lab exercise to help learn the equipment
But nowadays students demand to be spoon-fed and not exposed to the real world.

Meh. Some definitely do. I've seen students who, faced with a relatively challenging lab exercise, put their hand up and essentially ask for it to be designed for them. That's not what I'm talking about, though. Even for the ones who want to learn, you have to plan how to deliver information to them so as not to overwhelm them. Unfortunately, a few people think that if you put any effort into teaching methods beyond just bashing students over the head with information and expecting them to thirstily drink it up, you're spoonfeeding them, and some people think that if a student can be overwhelmed or doesn't just teach himself everything, he's demanding to be spoonfed.
but the rest was valid.
I'm becoming a grumpy old man.
There is another thread where generalisations about specific or small sample sizes were on topic. The "hobbyists are useless" thread. This thread has remained useful can we please keep it relevant for future reference?
