Figure 6-4: Representation of the AWGN blocks in System Configuration > Advanced Mode"
1 = Example of an 1x4x4 configuration
2 = Dedicated LEDs indicate the state of each stream
3 = Example of a 2x2x2 configuration
4, 5 = AWGN mode indication: AWGN indicates "AWGN Mode > Additive Nose/Noise Only", CW -
"AWGN Mode > CW Interferer"
6 = no AWGN mode indication in mixed AWGN streams configuration
The remote commands required to define these settings are described in Chap-
ter 14.19.4.5, "SOURce:AWGN Subsystem", on page 1088.

State
Activates/deactivates the generation of an AWGN signal. The interferer (AWGN or CW
interferer, depending on the selected mode) is generated after the generator is activa-
ted.
