R&S SMB100A
Remote command:
[:SOURce]:STEReo:RDS:TRAFfic:PROGram[:STATe]
RDS Traffic Announcement State - Stereo Modulation
Activates the RDS traffic announcement (TA function). If activated, the receiver
switches from the current status, e.g. playing a CD, to the receive mode and enables
the broadcast of a traffic announcement. The TP state has to be on.
Remote command:
[:SOURce]:STEReo:RDS:TRAFfic:ANNouncement[:STATe]
Adjustment Data
Indicates the adjustment state of the analog channels of the stereo coder. For the
adjustment of the S/P DIF see service manual, chapter 2, "Adjustment".

5.5 Modulation Generator and LF Output

5.5.1 Overview of LF Generator

The internal modulation generator of the instrument provides a sinusodial or rectangu-
lar LF modulation signal without additional equipment options. The corresponding key
data, as for example the frequency range, is specified under "Modulation sources" in
the data sheet.
You can use the internal LF signal as modulation signal source for the analog modula-
tions, as for example the amplitude modulation. The signal applies to all modulations
which are using the internal modulation signal. Therefore, any modification of the LF
signal impacts all currently active modulations immediately.
To configure the LF generator signal, see
on page 219. However, you can also configure the LF signal directly in the settings
dialogs of the analog modulations.
Optionally, the instrument provides the following modulation sources:
●
Pulse Generator (option R&S SMB-K23) for generating single and double pulse
signals, see
●
High-performance pulse generator (option R&S SMB-K27) for generating pulse
train signals.
The R&S SMB also provides the configured LF signal at the corresponding output con-
nector, for example as modulation signal source for interconnected instruments.
