Hi All!
I had to measure the Z profile on a certain power rail on a board. What I
did was I soldered some wires to power balls and some to ground balls, and
then soldered the other ends of these wires to a connector. I made sure I
had enough wires soldered for both power and ground, so the inductances of
the wires were in parallel with each other, and hence their effect was
minimized.
I used an Agilent 5071B Network Analyzer, and used the Z-Conversion
(reflection) feature to convert S params to Z params.
Do you think there is anything worng with way I thought out the
measurements? Is there any way this experuiement could be improved?
Since the calibration was done till the end of the SMA cable, I am thinking
I will take a frequency profile of the Z of the wires separately, and then
find way to divorce the effect of the inductance of the wires, from the
measurement.
Thanks for the guidance!
Regards,
Avtaar Singh
