Yes, I'm interested in RF signal processing. My application permitsIs there any ADC (Analog to Digital Conversion) board out there with
10MHz
conversion speed, 12-16bit resolution, 4Ksample conversion buffer and
USB
interface with QNX, Linux and Windows driver software?
If your really mean 10MSamples/second and 12 to 16 bits, you are
talking about transferring 120 to 160MBits of data per second.
That greatly exceeds USB 1.1 bandwidth, so you will need either
USB 2.0, or a big buffer and small samples.
Are you, perchance, working on digitizing radio IF or radar signals?
In that case, you might be able to find something with the buffer
to handle a few mS to a few hundred mS of signal.

Measurement Computing might have something that will go there.What I would like to find an ADC card with 10MHz sampling rate, 12-16 bits
resolution with enough memory/buffer to store at least 4K sample (8KByte)
data and being able to send the data via USB.
Thank you for the info.Measurement Computing might have something that will go there.
I'm using their PMD-1208LS for a battery charge system monitor, it's more
of
an "all in one" with analog in, analog out, digital I/O and counter. At
$79
it's a steal.

Yes, I'm interested in RF signal processing. My application permits
digitizing few mS long signal and transfer to PC for processing and
while PC processes the data digitize another few mS long singnal and
repeat these loop.
1 - Digitize 4K sample with 10MHz speed and 12-16Bits resolution
2 - Transfer to PC via USB (probably via USB 2.0)
3 - Goto 1

Do you know any board with such specs?
