The analyzer waveform packets are approximately 500bytes. The actual packet is less but typical TCP overhead without acceleration adds more so 500 is a good number for approximations. With a typical ethernet connection and analyzer Span the GUI can request and the analyzer can reply with 8 waveforms per second(Refresh Rate=8). So the network data rate is approximately 4000 bytes per second or 40kbps. If the analyzer is tuned down towards 0 MHz Span then the analyzer can generate up to 14 waveforms per second and the data rate rises accordingly.
