[Test generator] Can the fast transient/burst test generator FNS-AX4-A20/B63 apply to any selected phase, rather than applying to all phases simultaneously?

In addition to simultaneous application to all phases, the FNS-AX4-A20/B63 can also apply to any selected phase.
However, line-to-line testing requires the optional normal-mode coupling balun (15-00013A).
