The diagram displays the connection state of the tested connections.

10. Select "SGMA-GUI > R&S SGS > Freq = 40 GHz", "Lev = -30 dBm".

11. Select "SGMA-GUI >SGS> RF > State > On" to enable the output of the CW sig-

nal.

The extension adopts these values and states automatically and generates a CW
signal with RF = 40 GHz and Level = -20 dBm.

The signal is output at the [RF OUT] connector on the rear panel of the R&S SGU.
