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.
Remote command:
Channel Arrangement / Frequency
Sets the RF carrier frequency of the generator. The relation between operating band,
frequency and channel number is defined by 3GPP, 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.
Remote command:
Level (RMS)
Sets the base level of the generator. The individual physical channel levels are defined
relative to this base level, see parameter
The resulting actual Peak Envelope Power (PEP) is measured and displayed for infor-
mation when the generator is turned on. The indicated PEP corresponds to the actual
peak output level at the output connector, assuming the External Attenuation (Output)
is zero.
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 Level (RMS) is
decreased automatically.
Remote command:
Scrambling Code
Set index i (Primary) and index k (Secondary) for calculation of the primary and secon-
dary scrambling code numbers.
Primary scrambling code number: n = 16*i, where i = 0 to 1FF (hex), corresponding to
0 to 511 decimal.
Secondary scrambling code number: m = 16*i + k, where k = 0 to F (hex), correspond-
ing to 0 to 15 decimal.
Some channels can be scrambled using the primary or the secondary scrambling
code. If k=0 is entered, the primary scrambling code is used for these channels. If k≠0
is entered, the corresponding secondary scrambling code is used.
