Hello,
To remotely control your instrument, you can use e*Scope. E*Scope can be accessed through a web browser by entering the scope's IP address into the address bar. To easily capture and save waveforms, I would suggest using one of our software options as these actions are a little harder over e*Scope. I suggest you look into OpenChoice Desktop and TekScope Utility. These options are both free, but they use different Visa options. OpenChoice Desktop works with TekVisa and TekScope Utility works with NIVISA. Take a look at the links below to learn more about these two options.
