CONFigure:WCDMa:SIGN<i>:RFSettings:CARRier<c>:AWGN
<Enable>[, <Level>]
Enables or disables AWGN insertion via the signaling unit and sets the total AWGN
level within the channel bandwidth.
For dual carrier the same settings are applied to both carriers. Thus it is sufficient to
configure one carrier.
Suffix:
<c>
.
1..2
Selects the carrier to be configured - only relevant for dual car-
rier scenario
Parameters:
<Enable>
OFF | ON
Enables or disables the AWGN signal
*RST:
OFF
<Level>
The range of the AWGN level can be calculated as follows from
the range of the output power stated below:
Min (AWGN) = Min (Output Power) - External Attenuation
Max (AWGN) = Max (Output Power) - External Attenuation -
Base Level
Range:
-130 dBm to -5 dBm for the output power at RFx
COM, -120 dBm to 3 dBm at RFx OUT; please also
notice the ranges quoted in the data sheet
*RST:
-70 dBm
Default unit: dBm
Example:
See
Firmware/Software:
V2.1.30
Options:
R&S CMW-KS410
Manual operation:
See
CONFigure:WCDMa:SIGN<i>:RFSettings:CARRier<c>:GMTFactor?
Queries the ratio of the Output Channel Power (Ior) to the AWGN Noise power (Ioc).
INV indicates that AWGN noise is disabled.
Suffix:
<c>
.
1..2
Selects the carrier for which the information shall be queried -
only relevant for dual carrier scenario
Return values:
<Ratio>
Range:
-25.4 dB to 44.9 dB
*RST:
INV
Default unit: dB
Usage:
Query only
