2About the AM/FM/RDS Option
Use the AM/FM/RDS coder option to generate broadcast signals in FM and AM.
In FM, you can generate a mono or a stereo signal. For stereo signals generated
according to the multiplex method, an RDS coder is available and is used to code fixed
data. Many parameters can be changed over wide setting ranges. See Chapter 4,
"Audio FM Configuration and Settings", on page 17.
In AM, you can generate amplitude modulated signals. See Chapter 3, "Audio AM Con-
figuration and Settings", on page 12.
To generate an audio FM broadcast signal
1. Select "Baseband > Audio FM > State > On".
2. Select "RF > RF Level > State > On".

Preemphasis
Sets the preemphasis factor for the signal to noise ratio improvement.
To improve the SNR, the technique boosts high-frequency components at the modula-
tor and reduces them at the demodulator.
Example:
The level increase at an input frequency of 15 kHz and a pre-emphasis of 50 μs is
13.66 dB. At a pre-emphasis of 75 μs, the SNR is 17.07 dB.
The audio input level for audio generator and audio player therefore needs to be

The dialog provides general, MS, DI and CTRDS/RBDS settings.
The integrated RDS coder provides a versatile and flexible means of generating an
RDS data stream. It enables data for all the important group types to be entered as
menu inputs.
For group types provided for ODA, see Chapter 4.6.2, "Open Format Settings",
on page 49. You can define the data content of blocks 2, 3 and 4 using hexadecimal
input. The all-purpose input design means that there is no need to distinguish between
RDS and RBDS.
Defines the group sequence, that specifies the order of groups.
The group sequence is mandatory within the RDS data. The input field accepts up to
38 groups. A group consists of a group number and a version ("0A" to "15B"). Separate
groups by setting a comma or a space.
If you enter a group number without specifying version A or B, the software adds version A automatically.

The RDS/RBDS transmission rate is approximately 11.4 group types per second. For
this reason, the repetition rate per time unit is determined decisively from the group
sequence inputs.
Note: Settings on the "RDS/RBDS" tab only take effect, if you enter the related group
in the group sequence.
Once the entered groups have been fully transmitted, the group sequence is repeated.

PI
Sets the program identification, that is a 16-bit value in hexadecimal representation.
The usage differs for RDS and RBDS operation:
●
RDS: The PI consists of a code enabling the receiver to distinguish between countries and regions in that the same program is transmitted, and the programs themselves.
It 16-bit value comprises the country code (bit 15 to bit 12), the program type (bit 11
to bit 8) and the program reference number (bit 7 to bit 0).
●
RBDS: In North america, the program identification code is used differently. In part,
the broadcasting stations define the program identification code themselves.
The PI is transmitted in each group type. For A group types, the PI is transmitted in
block 1. For B group types, it is transmitted in block 1 and block 3.
Remote command:
[:SOURce<hw>]:BB:RADio:FM:RDS:PI on page 67
PS
Sets the program service name.
Group types "0A" or "0B" transmit the PS in addition to the PI. The PS is transmitted in
block 4 in both version A and version B.
You can enter an 8-character PS code, e.g. "R&S SMCV". For allowed character sets,
see Figure A-1.
Note: Not all receivers can display the full character set. For an overview of the dis-
played information, see Table A-1 and Table A-2.

"B"
Alternative frequencies are transmitted using method B in the following cases:
●
The transmitter and its associated repeaters have more than 25
alternative frequencies.
●
Several local regions have different program content.
In such cases, the respective alternative frequencies are transmitted
as alternatives to several transmission frequencies. Frequency information is transmitted in the form of frequency pairs, giving the set
transmission frequency and the associated alternative frequency in
each case.
The sequence of the frequencies is important in this method. Sometime the higher frequency is transmitted first, which refers to a frequency having the same program content (ascending). If the lower
frequency is transmitted first, a regional variant using the alternative
frequency is being transmitted (descending).
Frequencies from the LW and MW bands are not supported.
Example: Applying method B
A list containing 5 different alternative frequencies is transmitted
using method B.
Block 3 of the first group type "0A" specifies the number of frequencies that follow and the transmission frequency to which the alternative frequencies are referenced. The number of frequencies to follow
is therefore 11.

Use the settings to send traffic messages as single group messages or multi group
messages.
A single group message is transmitted in one group type "8A", a multi group message
needs up to 5 group types "8A". It can take up to 6 group types "8A" to transmit the
tuning information.
TMC transmission is announced in group type "3A". We recommend that you send
group type "3A" at regular intervals.
TMC data messages are coded as specified in EN ISO 14819-1.

The data you entered is accepted.
The behavior depends on "Open Format", see "Open Format"
on page 49:
●
"Open Format > On": If the "Group Sequence" includes group
types "3A" and "8A", the last 5 bits of block 2, as well as blocks 3
and 4, are filled up with zeros.
●
"Open Format > Off": You can edit the group types "3A" and "8A"
without restriction.
Block 3 table
The settings in the table take effect, if "TMC > Off".
The table contains rows "Group 3A Var. 00" and "Group 3A Var. 01". Both parameters
comprise 16-bit values in hexadecimal representation.
In principle, group "3A" is sent in turn with variant 0 and variant 1. The input data is
held in block 3, see Table 4-3 and following sections.
The last 5 bits of block 2 are transmitted with the group application code "10000".
Block 4 of this group type is stuffed with 0xCD46. This code tells the receiver that the
following group types 8A contain TMC information.

Tuning information
This feature is not for transmitting the content of traffic messages. Instead it carries
general information about the TMC service, such as the service provider name, the
associated program identification, the assigned frequency and various system
parameters.

Apply
Sends the TMC message.
Since it takes a certain amount of time to send a TMC message, during the transmis-
sion process, an hourglass symbol is displayed left from the subtab name and the
"Apply" button.
When using remote control, it is particularly important to know whether a message that
has been entered has yet been transmitted and when a new TMC message can be
sent.
If the group types "3A" and "8A" are not included in the "Group Sequence", an error
message is displayed. The transmission stops until the group types "3A" and "8A" have
been entered.

6Remote-Control Commands
The following commands are required to generate signals with the AM/FM/RDS option
in a remote environment. We assume that the R&S SMCV100B has already been set
up for remote operation in a network as described in the R&S SMCV100B documentation. A knowledge about the remote control operation and the SCPI command syntax
are assumed.
Conventions used in SCPI command descriptions
For a description of the conventions used in the remote command descriptions, see
section "Remote-Control Commands" in the R&S SMCV100B user manual.
Common suffixes
The following common suffixes are used in the remote commands:

Programming examples
This description provides simple programming examples. The purpose of the examples
is to present all commands for a given task. In real applications, one would rather
reduce the examples to an appropriate subset of commands.
The programming examples have been tested with a software tool which provides an
environment for the development and execution of remote tests. To keep the example
as simple as possible, only the "clean" SCPI syntax elements are reported. Non-executable command lines (e.g. comments) start with two // characters.
At the beginning of the most remote control program, an instrument preset/reset is recommended to set the instrument to a definite state. The commands *RST and
SYSTem:PRESet are equivalent for this purpose. *CLS also resets the status registers
and clears the output buffer.
The following commands specific to the AM/FM/RDS are described here:
●Audio AM Commands............................................................................................. 56
●Audio FM Commands............................................................................................. 60
