Manual Expected Power
Expected absolute input power at the R&S
CMW input connector for "Expected Power
Mode: Manual". Input powers above the "Manual Expected Power" overdrive the input
path and cause invalid results.
Remote command:
CONFigure:CDMA:SIGN<i>:RFPower:MANual
Expected Nominal Power
Displays the expected nominal power that the MS has to transmit. The value depends
on to the selected "Expected Power Mode". The value is displayed for information.
Note that the actual input power at the connectors must be within the level range of the
selected RF input connector; refer to the data sheet.
Remote command:
CONFigure:CDMA:SIGN<i>:RFPower:EXPected?
AWGN Mode
Selects operating mode of the AWGN generator. The AWGN generator provides an
Additional Gaussian White Noise signal which is superimposed to the forward
CDMA2000 signal. The AWGN contribution represents a controlled impairment of the
forward signal.
The "AWGN Level" range is adjusted to the selected mode.
●
Normal
: appropriate for low and medium AWGN levels.
●
High Power
: appropriate for high AWGN levels. It requires option R&S CMW-
KS810.
Remote command:
CONFigure:CDMA:SIGN<i>:RFPower:MODE:AWGN
AWGN Level
Specifies level of the Additional White Gaussian Noise (AWGN) interferer relative to
the "CDMA Power". The signaling unit adds the AWGN signal to the forward signal
unless AWGN is switched off. Like the output channel power, the AWGN level is varied
as a function of the external output attenuation setting.
The range of values is sufficient for the 3GPP2 conformance tests. An AWGN signal
source simulates realistic propagation conditions of the forward signal.
The signal at the output connector is limited to the maximum level stated in the data
sheet. When the settings result in a signal exceeding this limit, the AWGN noise is
decreased automatically.
Disable this parameter for fading scenarios, so that AWGN can not be added by the
signaling unit. Instead AWGN can be added by the fader (external or internal).
Remote command:
