Dynamic fading (R&S ® SMW-K71 option)
At least one R&S ® SMW-B14 fading simulator must be installed. If two or more R&S ® SMW-B14 are installed (signal paths A and B),
dynamic fading functions can be used either on signal path A or B with one R&S ® SMW-K71 option. For dynamic fading functions to be
used on signal paths A and B simultaneously, two R&S ® SMW-K71 must be installed.
