What's the standard way to measure crosstalk in the lab? We have
experimentally determined that there is crosstalk on our PCB due
to traces being too close together for an xDSL system on the analog
side. We want to characterize the amount of crosstalk between two
'bad' ports vs. two 'good' ports
to determine if our respin will work properly in simulation.
The frequency band of interest is between DC and 1100 KHz, which seems
like it should not be succeptable to crosstalk very much, but we have
experimentally determined
that if we re-route the tracks of interest using rework wire we can make
the crosstalk go away.
Would a spectrum analyzer and a signal generator be the way to go, or
perhaps a network analyzer to check the rejection ratio?
Could we do this via simulation as well?
