8.3 How to define the signal at the REF/LO OUT connec-
tor
The reference oscillator and the LO use the same "REF IN" connector. Hence, it is not
possible to use both an external reference source and an external LO source signal at
the same time.
The signal at the "REF OUT" connector also depends on the selected reference oscil-
lator and LO sources. The following table gives an overview of this dependency.

Ref. oscillator source

"Ext"
To define the signal at the REF/LO OUT connector
1. In the "Frequency / Phase > Local Oscillator (LO) Coupling" dialog, select the "LO
Source" as required.
2. In the "Reference Oscillator" dialog, select the "Ref. Oscillator Source" as required.
3. In the "Frequency / Phase > Local Oscillator (LO) Coupling" dialog, set the
"REF/LO Output".

8.4 How to create and save ARB test signals

If your test case requires a simple sine or square test file, consider to use the provided
ARB test signals.
1. Select "Baseband > ARB >General"
2. Select "Create Test Signal > Sine".
3. In the "Sine Test Signals"dialog, adjust the settings as required.
4. To create the test signal file, proceed as follows:
a) Select "Generate Signal File".
b) Navigate through the directory tree (e.g. /var/user/).
c) Enter a file name (e.g. sine_waveform).
d) Select "Save".
The R&S SGT saves the generated waveform file and automatically loads it in the
ARB.
