Example: Generating a beamformed signal with two one path Rohde & Schwarz
Signal Generators
This example shows a test setup with two generators, each equipped with one path.
Generator 1 = "Internal"; "LO OUT > On"
Generator 2 = "External"; "LO OUT > Off"
The Signal Generator 1 uses its internal oscillator signal. Signal Generator 2 receives
the LO signal from the first instrument. The frequency is assumed to be 2 GHz.
Example: Generating a beamformed signal with two Rohde & Schwarz Signal
Generators
This example shows a test setup with two generators, each equipped with two paths,
like for example the R&S SMW or the R&S SMU200A.
Figure 8-6: Set up of LO coupling with two Rohde
&
Schwarz Signal Generators
Generator 1 = "A Internal & A->B Coupled"; "LO OUT > On"
Generator 2 = "A External & A->B Coupled"; "LO OUT > Off"
The signal generator 1 uses the internal oscillator signal of path A also in path B. The
signal generator 2 receives the LO signal from the first instrument and assigns it to
both paths. The frequency is assumed to be 2 GHz.
Depending on the required RF frequency, your instrument may not be adequately
equipped in one of the paths.
If so, you can adjust the LO coupling mode accordingly to use the LO signal from the
other path. Proceed as described in Configure Signal Generator 2 in the example
"Cascading three Rohde & Schwarz Signal Generators".
