A = Example of an 1x4x4 configuration
B = Example of a 2x2x2 configuration
1 = Dedicated LEDs indicate the state of each stream
2 = no AWGN mode indication in mixed AWGN streams configuration
3a, 3b = AWGN mode indication: AWGN indicates "AWGN Mode > Additive Nose/Noise Only", CW -
"AWGN Mode > CW Interferer"
The remote commands required to define these settings are described in Chap-
ter 13.18.4.6, "SOURce:AWGN Subsystem", on page 1001.

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.
Remote command:
[:SOURce<hw>]:AWGN:STATe on page 1005
Coupled Mode
Couples the configuration of all streams.
Note: In the default state of the AWGN, this parameter is enabled. We recommend
that you configure the AWGN settings in coupled mode.
When you disable the coupled mode, the instrument does not apply the current set-
tings to all streams. The settings of the individual streams are in the state they ware
before the coupled mode was enabled.
See also "Joint configuration of all streams" on page 394.
Remote command:
[:SOURce<hw>]:AWGN:CMODe[:STATe] on page 1005
Mode
Selects the mode for generating the interfering signal.
