[SI-LIST] Separating SSO contributed by board vs device

I'm trying to quantify the amount of SSO noise which is contributed by
the pc board power delivery system (vias, decoupling, stackup), with the
goal of separating this noise from the SSO noise which is contributed by
the device and its package.
Has anyone attempted to measure this effect, and if so, what would be a
good technique? I have two boards available, one with devices populated
and the other with some BGAs depopulated, so I have access to the vias.
Thanks and regards,
