In the Standalone (SA) scenario, these parameters are controlled by the measurement.
In the Combined Signal Path (CSP) scenario, they are controlled by the signaling appli-
cation.

Frequency Offset
Offset that the R&S
CMW adds to the "Frequency".
In the Standalone (SA) scenario, this parameter is controlled by the measurement. In
the Combined Signal Path (CSP) scenario, it is controlled by the signaling application.

Expected Nominal Power
Defines the nominal power of the RF signal to be measured. An appropriate value for
CDMA2000 signals is the peak output power at the DUT during the measurement inter-
val. The "Ref. Level" is calculated as follows:
Ref. Level = Expected Nominal Power + User Margin
The actual input power at the connectors must be between -47 dBm and +55 dBm
(please notice also the ranges quoted in the data sheet). If all power settings are con-
figured correctly the actual input power equals the "Ref. Level" minus the "External
Attenuation (Input)" value.
In the Standalone (SA) scenario, this parameter is controlled by the measurement. In
the Combined Signal Path (CSP) scenario, it is controlled by the signaling application.

User Margin
Margin that the R&S
CMW adds to the "Expected Nominal Power" in order to deter-
mine its reference power ("Ref. Level"). The "User Margin" is typically used to account
for the known variations of the RF input signal power, e.g. the variations due to a spe-
cific channel configuration.
The appropriate values depend on the configuration of the RL CDMA2000 signal, e.g.
on the active channels and gain factors. A typical value for the user margin is 9 dB.
