Determining wether you have a board generation I or II

[spacef]

I have read some post in the "scope purchasing" that show that people do not know how to determine for sure if they have Board of generation I or II.

The easier way to determine for sure wether it is I or II is the ulli and samplerate it can deal with.

Board I lowest latency is line 2 (from bottom), whereas all latencies are available with a board II. Also Board I cannot do 96 khz sampling. There are also other differences, but harder to quantify, or not essential ones.

In the pictures, "board I & II " refer to board of generation 1 and generation 2. generation 1 was released in 1998 and replaced by generation 2 in year (... 2000 ? not sure ).

PS, a little mistake in the ulli picture: a board I cannot do 96khz (it can do 32/44/48 only i think).

Hi Spacef,

I've been wondering for a while if there's really 3 (or more?) generations of board. The reason is that as far as I know there were 2nd gen pro cards with 15 dsp chips, then came the boards with 14 chips. Am I missing something?

best regards,

That's what I thought the case was from what I've read on PlanetZ. It's been mentioned around the forum as working that way quite often, but I don't quite follow why the 15th all of a sudden wasn't needed. Further to that, our new 14dsp card bought from CW just before Xmas seems to think that it has 15 dsps ...

Anyway, I just thought it was worth mentioning that there might have been more than 2 generations of board. At least it would look that way to me.

Thanks !
I determined now my scope is of I type.
Great info !

I think ALL boards (scope/srb) have 15 dsp (the number 15 will be displayed in the dsp meter, but only 14 individual dsp meters are showed - even for cards with 14 physical dsps). In fact i heard of no board with 14 dsps displayed on the dsp meter (all of them will report 15 dsps (or 30 or 45 if you chain them) and all of them will show 14 individual dsp meters (or 28 or 42)... that's what i noticed on various setups i have been able to manipulate.
But i do not know all cards neither... so may be there are other versions.

I both have a card with "generation 2" card 15 physical DSPs and one with 14 physical DSPs.

Ok, that was pretty bad gramar due to fiddling too much with the post. Here goes a more readable version:

Our card also has 14 physical chips, but it's an srb so maybe that's why it's minus a chip? Strange if it's only the 2nd gen srbs with 14, as I thought the only difference between the srb & pro board (apart from software) was the I/O plate.

Stardust, I counted the chips as it slid out of the new Scope packaging for the first time

Anyway, SFP thinks it has 15 chips, but it most certainly only has 14.

The 14/15 dsp thing has nothing to do with the card being SRB or "normal" card. My 15 dsp card (from 2001, if I remember right) was bought new directly from Creamware as an SRB card.

always something new to learn about Scope...even in 2007
