"External
(Direct
Access)"
Use the signal from the source out (direct access) of the lower tone
port and the signal from the upper tone port, combine them externally,
and feed the combined signal to the source in (direct access) of the
lower tone port:
With this configuration, the two-tone signal is available at test port 1.
The intermodulation quantities can be measured at the DUT input or
at the DUT output.
"Use Coupler
as Combiner"
This configuration does not require an external combiner, but pro-
vides a reduced dynamic range. It combines the signals of the lower
tone and upper tone sources using the directional coupler of the
upper tone port as combiner:
With this configuration, the two-tone signal is available at test port 1.
The intermodulation quantities can be measured at the DUT input or
at the DUT output.
