LabVIEW Express 7 and PXI-5122

[enekofg]

Hello.

I'm involved in a project which aim is digitizing the signals received
from several(2 at the beginning) antennas. We pass these signals to an
intermediate frequency of about 15 MHz.

Now we want to use the NI-5122 to DIGITIZE these signals and after
that GENERATE a response.
The questions are(I know the hardware for generation has not been
specified):

1.- Is the material(LabVIEW and PXI-5122) appropiate for the
task?(there could be more antennas in the future) (LabVIEW running in
Windows 2000(multi-task) and sharing the bus PCI of the computer with
other cards also)

2.- Can we have troubles of time, in order to process the signals at
these rates(30MS/s minimum,5122 is a 14bit resolution digitizer, if
I'm not wrong)

3.- Should be Real-Time used?

4.- Would the bus PXI and PCI be a problem(I refer to the transfer
rate) when working with both channels and at these rates in a
continuous way?

5.- In order to generate the signals, could we use the NI-5411
Arbitrary Waveform Generator?

Thanks a lot.

Re: API's & drivers

Thanks a lot Brian!!!
Another little question to finish:
NI-SCOPE(API) can use both NI-DAQ(driver) and NI-DAQmx(driver). Then
why NI-SCOPE(API) and not NI-DAQmx(API) or NI-DAQ(API)? Why use
NI-SCOPE and NI-FGEN (APIs), in my case, and not NI-DAQ(API) and
NI-DAQmx(API)? Which are they advantages? Just being easier to use or
learn(because they have a more limited set of functions)?

API's & drivers

[enekofg]

Hello.

I'm already a bit confused when reading about drivers and APIs...
What's the difference between an API and a driver???(because sometimes
texts refers to some of them without distinction).

Once known the difference, which is which? NI-DAQ is a... driver or
API???
And this for NI-DAQ, NI-DAQmx, NI-SCOPE, NI-FGEN, NI-DAQ 7.

For what I think I understand NI-DAQ and  NI-DAQmx are both drivers
and APIs, and NI-FGEN and NI-SCOPE just APIs. If I'm not wrong, why 2
APIs for one driver???

Thanks.
