boradband scope with hig impedance input from each line to ground, assuming
the conductors are carrying AC. The voltages from each side to ground should
be nearly identical if the common mode currents are close to the same

I would disconnect the battery from the test.

Do not remove the battery unless the computer has been designed to be used
by the customer without the battery.The test should be performed on the
computer as it will be sold and used. If the computer is always used with
the battery installed, then that is the way to perform the test.

Gentlemen,
Thanks for your advice. A little more to this product if I may add some
information. It is mains powered and is primarily intended for a domestic

Generally, low frequency is dominated by differential mode caused by the
