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.

Adjustment Data
Indicates the adjustment state of the analog channels of the stereo coder. For the adjust-
ment 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
An LF generator providing sinusoidal and square signals in the frequency range 0.1 Hz
to 1 MHz is available for the basic unit without additional equipment options.
The LF-Generator is the internal source for the analog modulations AM, FM and PhiM,
and provides the signal also at the LF output (front) of the instrument.
The frequency setting for the LF generator can be made both in the modulation dialogs
and in the "LF Generator / Output" dialog. The settings are effective for all modulations
using the internal modulation source.
A change to the frequency of the LF generator automatically has an effect on modulation
if the LF generator is selected as the modulation source (i.e. "Internal" is selected as
"Source").
The LF Sweep mode is activated in the "LF Frequency Sweep" dialog (see chapter 5.5.3,
"LF Frequency Sweep", on page 189). "RF frequency" and "RF Level" sweeps are acti-
vated in the respective dialogs of the RF block.
The option Pulse Generator (R&S SMB-K23) enables the generation of single and double
pulse signals.
Option (R&S SMB-K27), Pulse Train, enables generation of pulse trains.
The generator is activated and configured in the "Pulse Generator" dialog of the "Mod
Gen" block or in the "Pulse Modulation" dialog of the "Modulation" block ("Pulse Gener-
ator" is selected as "Source").
5.5.2 LF Output
To open the "LF Generator / Output" dialog, select "Mod Gen" > "Configure" > "LF Gen-
erator / Output" or use the MENU key under "Mod Gen".
