Hi Eldad,
Thanks for posting and welcome to the NI forums!
The
application you have linked uses LabVIEW to control a Tektronix TDS220
over RS232 (a.k.a. serial port). The TDS220 has a 1GHz sample rate
with a 100 MHz bandwidth--the specs on our DAQ devices don't go nearly
this high, our High Speed Digitizers
would be a better option if you need something comparable. Also, the
programming of the two devices (TDS220 vs. DAQ) is going to be quite
different, so I am not sure how helpful the code from the link would be
for your application. I don't have access to the code or permission to
post it here, but you could always try contacting the original author
(his contact info is in the link you provided, not sure if it's up to
date or not). Again, I'm not really sure how helpful the code would be
for you.
You might want to take a look at the following example to see if it does what you need:
NI-DAQmx: Benchtop Spectrum Analyzer
There
are also numerous examples that are installed with the DAQmx Driver to
help you get started with the API. You can access them from LabVIEW by
going to:
Help >> Find Examples... >> Hardware Input and Output >> DAQmx
There
may not be a ready-made example that will do everything that you
require, but the above should give you a good starting point for
implementing the necessary features yourself. If you run into any
specific issues while trying to program, please don't hesitate to post
to the forum and we'll be more than happy to help out.
