Hi Andrew,

Thank you for the response. I did the followings:
1. I read about power issue in this forum and I supplied power to USB hub from PSU, both drawing ~1.16A @ 12V, and Spike was stable without disconnection.
2. However, VSG60 became consistently disconnected after RF On/Off cycle on Step Sweep.
3. As suggested, I played around with other configuration e.g. Ramp Sweep, it work without issue.
4. I went back Step Sweep configuration and found that if I changed the Dwell time to 1us, it ran (RF On) but hang (see attach screen shot) for a second when I stopped (RF Off) it.

Therefore, it seems like Dwell Time of 1us coupled with power issue made both units unstable and unpredictable I encountered initially.

Additional note, I ran both VSG60 and Spike on Dell Precision 5540 via Dell Thunderbolt 3.0. I don’t think bandwidth will the issue.
