I had a problem when trouble shooting a servo system that had a position servo in one location driving a servo amplifier in a distant location.
The servo amplifier had its own speed control loop and interaction between the two loops cause insability a certain speeds.
The problem was that I needed to see the response of the servo amplifier when making adjustments to the position controller.
I solved this by purchasing a BELKIN F5L009uk network usb hub, this when pluged into a network appears to any computer on the network that is running the Belkin software as a USB hub. I then plugged in the Picoscope 2205 to the network hub and connected to it using the Belkin utility, the Picoscope was then enumerated as normal and then by running Picoscope the remote waveform could be monitored !.
This technique could of course be extended so that a remote Picoscope could be controlled over the internet
(Very usefull in the depths of the English winter).
I don't know what are the limitations of this technique but it certainally worked for my applicatition.
