Remote Control for all of the 'DSA700/DSA800 Series' Spectrum Analyzers. Its nice for basic control (Center Freq., Start/Stop Freq., etc), and especially for monitoring the DSA on a PC, and really awesome with a large external LCD Display attached to the PC.
I suggest trying Peter Dreisiebner's (EEVblog'er 'PeDre') 'Rigol DSA800 Remote Control LAN/USB' that is available at:
https://translate.google.com/translate?hl=en&sl=de&u=http://peter.dreisiebner.at/rigol-dsa815/index.htm (English language), or
http://peter.dreisiebner.at/rigol-dsa815/index.htm (German language).
This is a Portable program, meaning that you simply run it (from any directory, the desktop, USB drive, etc) and it works directly without requiring any installation, or its making changes to the Windows Registry. The only preparation you need to do on the PC is to add a Win USB driver 'Zadig v2' available at
http://zadig.akeo.ie/. This USB driver is required for any of Peters Dreisiebner's programs. It isn't required for LAN, although I prefer USB, seems faster/easier to me, and the driver is easy to install.
I use the program with Windows 10 and it is great. I want to point out that this program has not been fully completed, and it may never be (?), so there are functions that are not available, such as Marker, Measurement, Tracking Generator, SSC, and possibly a few others. But don't be too concerned, because you can temporarily set 'Remote' - Off, 'Select Trace' - Stop. Then press 'Esc' on the DSA, and make the any desired SA selection changes manually (via Front Panel). Then set the 'DSA800 Remote Control' to 'Remote' - On, and 'Select Trace' - Run. This sounds more complicated than it actually is, and once you have tried it I think you will agree.
Note that this program also provides some very nice options. i.e. 1.) Spectrogram/Waterfall Display under its normal SA display. 2.) Cross-hair (cursor) display for the SA Remote screen's display cursor. And as standard, a nice presentation of the current configuration, etc.
You may find a couple of bugs in the program, although if so you will learn how to either avoid, or recover from them quickly. I think you will agree that this program is awesome for monitoring the SA on your PC, or better yet with a large screen LCD monitor attached to the PC.
Edit: I can't say enough about how nice this program is, and easy to use. The only thing that requires installation is the small USB Zadig driver, if it isn't currently on your PC.
