FWIW, I have been using a USB 3 fiber extender (an Icron unit) to connect a BB60C that is on the roof right at my antenna, about 100-foot cable run away, to my computer in the lab a couple of stories below. This saves me about 7 dB of LMR-600 cable loss at 3.5 GHz, compared to locating the BB60C in the lab.
The USB 3 extender has worked very well for several years, although starting about two years ago, an update to the Signal Hound USB drivers or Spike or both caused it to become less reliable. The BB60C would disconnect every few minutes. I rolled back my drivers and Spike version and it works 100% again now. The only drawback is that now I’m “stuck” with a Spike version that is a couple years old, for this particular installation.
For deployments that are in other locations (i.e., many miles away), I connect a BB60C to a co-sited laptop, and I remote into the laptop using Splashtop. This is reliable, although the frame rate achieved on any remote application I’ve tried is not good enough to keep up with the refresh rate needed to see every single sweep in Spike. But I record the data coming from the BB60C and upload it to the cloud so I can play it back locally for full performance.
