This is from the (potential) client's original email:

"There is the unique 200 mA test method in EN 55103-2:2009, fig. B.3b) and
B.4 which uses a "toroidal transformer" for injection beginning at 50 Hz."

He then states:

"I do not like the method's uniqueness and the lack of an usual calibration
procedure."

And he goes on to say he wants a bulk cable injection technique similar to
MIL-STD-461 CS114.  That's where the the thread was punted my way.

It's not too hard to inject 200 mA into a dead short, but as stated in the
original post, there must be some way to bound the driving potential as
well. A BCI technique at low audio frequencies is non-trivial if a potential
of any magnitude must also be delivered.

Thank you,
