Colleagues:

What is the simplest way to test the bare board resonance? use a 50
Ohm resistor in series with the power and or ground plane, drive it
with a sweeping oscillator and observe using a Spectrum analyzer
connected with a "T"?

SG----50ohm---PCB

SA-----------


In this configuration, the pcb appears as a stub to the 50 ohm line
from the SG to the SA. It seems it would work but?.. there probably
are many better ways?

Thanx in advance
