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.

Example:
ROUTe:CDMA:SIGN<i>:SCENario:SCELl
External Attenuation ← RF Input (RX)
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.

RF Frequency
This section configures the band class and channel/frequency for forward and reverse
links. Additionally frequency offset is set.
Fig. 4-36: RF frequency settings
Band Class, Channel, Frequency
Sets the RF channel of the forward carrier. "Reverse Link Frequency" displays the cen-
ter frequency of the RF analyzer and "Forward Link Frequency" the center frequency of
the generated 1xEV-DO signal.
To specify the center frequencies, select a band class first, then enter a valid channel
number. The resulting frequencies are calculated automatically.
The relation between operating band, frequency and channel number is defined by
3GPP2. For an overview of available band classes see
.
