Shareware O-scope for use with National Instrmt DAQs?

[Scott Kelley]

I need to work with audio signals, down to and *including* DC (so
sound-cards are out). Have found a relatively low cost data acquisition
device ($245 National Instruments USB-6009) that will do what I need on the
hardware side.

I'm now looking for a shareware oscilloscope & spectrum analyzer program
that will work with this device. I know I've seen at least two in past
years that can utilize the National Instrument devices but can't track them
down now. Any thoughts?


Thanks,

You might peek at www.dataq.com and their $24.95 starter kit WITH software.
The software is more "chart recorder" than "scope/spectrum analyzer" but
it might do what you want.

You may have some luck trying to get sample LabView program which could
be used with National Inst'a free runtime library.

I use "DPLOT" www.dplot.com It won't show you real time graphs, unless you
write your own capture software (VB) which is very doable. If you are
running a capture, and then break the data out into dplot, it can do allot
of computation for you, fft dft, etc... Capture can be in many different
formats, including "comma-separated-values (csv)". It's worth a look, around
$30 for full version, Dplot jr is free.
