Hi casillasr,
In searching the NI Instrument Driver Network (www.ni.com/idnet), I did not find this specific model of Tektronix Spectrum Analyzer, but I did find some drivers for different model numbers. You may be able to change some of
these drivers to work with this specific application, but since I have never used the RSA 3308A, I do not know if it is similar enough to the other models to simply modify the code.
If you would like to create your own application to communicate with the analyzer, the hardware/software requirements are not excessive. You will definitely need a version of LabVIEW in order to create a program in the LabVIEW environment. Most of these external instruments communicate using GPIB, so you would also need a GPIB interface of some sort on your computer, along with the associated 488.2 driver. Then you will need to look in the manual to see what commands to send to your instrument to receive the proper information. National Instruments makes several different GPIB products, and you can find more about them
here.
Good luck with your application! Let us know if you need help along the way.
