Finally had a chance to download the manual. I can see no reference in the user manual for remote control except through the GPIB port. It looks like the USB ports are for connecting a mouse or keyboard and the serial port is for connecting other peripherals. On the page that describes the TDS 5000 characteristics, there is a mention that the OpenChoice software includes a VXI-11 server. VXI-11 refers to instruments with a network connection. It's possible that you can use this to control the instrument. You configure an Ethernet connection in MAX. Select Devices and Interfaces, right click, and Select New>VISA TCP/IP Resource. I really don't know if this will work. I'm just telling you that if the instrument does support it, this is how to get started. At this point, it might be better for you to contact Tek directly.
