Test & Measurement interface for Soundcard

[FastEddy]

Mmmm ... never upgraded to W/7 ... several machines at the office w/XP ... and a plethora of Macs at home and office

I was forced... I switched jobs (I started working as a freelancer), so I had to buy new pc's and licences. As it is almost impossible to buy new pc with XP preinstalled (only some very $$$ models), I bough a pc and laptop with win7.

I started out with 64bit, but I had to chane to 32 bit because a lot of software confilct with old automation software programs. 32bit is ok for most of them.

Hello,
i got my pcb the other day in the mail, THANKS Pete!
I spent last sunday populating the board, and it looks like everything is working apart from the digit points.
they are all on
i used a different Panel, its from a local supplier here in Germany, and it looks like the bpn pin delivers only 2.6V.
if i understand the function of the logic gates, 2.6V is not "high" enough to switch the output of the gate to 0V if the second input on the gate is taken to 0V by the switch.
would a different Logic IC help (one with a lower min VH than the original with VH min>3,2V)?
Thanks for your help,
Yurgs

i've got the datasheet of the panel attached, and the datasheet of the oiginal IC is here: http://www.ti.com/lit/ds/symlink/sn74hc86.pdf

Gee, I have the 1212m PCI (not PCIe) - never got it to work properly, but I wasn't using ARTA. My results were never that good! Windows 7, 32-bit.

I will have to try again!

anyone got an idea how something like this would perform as an interface ( connected to the spdif in on the mainboard).
Non-Oversampling DAC TDA1543 DIR9001 96kHz SPDIF Coax Optical & 9V NiMH charger | eBay

i tried the laptop card and that was a disaster....
or should i just get a decent soundcard

PS, i solved the problem from my posting above, the imterface works fine now!
cheers

I think you need an ADC instead of a DAC

FCK me, i was playing with ideas and got totally stuck here,
shame :-)
thanks anyway!PS i will not worry about the signal gen side of it

Hey _Wim_,

Have you tried this with AudioTester? Seriously thinking about the 1212 after seeing your results and given the fact I am short on PCI slots but have plenty of PCIe.

thanks,

Andrew

Nope, never worked with that software. I expect the results to be very comparable however.

Hey there,
i had some success using ARTA and Autdiotester, but my soundcard drivers seem to be limited to 22kHz, how can i get the card to work with more bandwidth ? its the same with the M.Audio 192 and the onboard card
