RF Routing
Selects the input path for the measured RF signal, i.e. the input connector and the RX
module to be used.
Depending on your hardware configuration there may be dependencies between both
parameters. Select the RF connector first. The "Converter" parameter offers only val-
ues compatible with the selected RF connector.
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.
For connector and converter settings in the combined signal path scenario, use one of
the
ROUTe:WCDMa:SIGN<i>:SCENario:...
signaling commands.

External Attenuation (Input)
Defines the value of an external attenuation (or gain, if the value is negative) in the
input path. The power readings of the R&S
CMW are corrected by the external attenu-
ation value.
The external attenuation value is also used in the calculation of the maximum input
power that the R&S
CMW can measure.
If a correction table for frequency-dependent attenuation is active for the chosen con-
nector, then the table name and a button are displayed. Press the button to display the
table entries.
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 3GPP (see
ter 3.2.4.3, "Operating Bands"
Option R&S CMW- KB036 is required for frequencies over 3.3 GHz (OB22).
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.
