Operation with more than one source is not supported, if External switch matrices are
part of the RF connection configuration.
The intermodulation distortion measurement can be extended to frequency-converting
DUTs. E.g., it is possible to feed the two-tone source signal to the RF input of a mixer
and measure the intermodulation distortion of the IF output signal, after conversion
with an additional LO signal.
