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.

Band / Channel / Frequency
Center frequency of the RF analyzer. Set this frequency to the frequency of the mea-
sured RF signal to obtain a meaningful measurement result.
The relation between operating band, frequency and channel number is defined by
3GPP2 (see
You can specify the RF frequency in two ways:
●
Enter the frequency directly. The band and channel settings can be ignored or
used for validation of the entered frequency. For validation select the designated
band. The channel number resulting from the selected band and frequency is dis-
played. For an invalid combination no channel number is displayed.
●
Select a band and enter a channel number valid for this band. The R&S
CMW cal-
culates the resulting frequency.
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
