No, it's quite simple. If the turns ratio is 5:1, then the Z ratio is 25:1.

As long as the 2 baluns have the same transformation ratio ( i.e. 9:1,
25:1)
this is perfectly valid test.

Hi Dale,

I think David's point was that you can prove symmetry through the back
to back test, but you don't "know" what it is symmetrical about. Was
that 9:1's we were testing, or the 25:1's?

I can imagine a 25:1 transformer, but I sure haven't seen the
configuration for a 25:1 BalUn - that has to be one nasty mess of
connections staged across several compound BalUns.
