To show a demo:
1.
Press the [Apps Selection] key.
2. Select the "Applications" tab.
3. Select "Demo".
4. Select the "Track" tab.
5. Select the signal.
6. Connect the demo signal to the input channel as shown in the wizard.
7. Tap "Start".
7.2.6.3 Example signals for tracks
If the signal generation option R&S RTA-B6 is installed, you can use the pattern gener-
ator to generate PWM signals, see Chapter 16.2.7, "Settings for PWM signals",
on page 420.
To get familiar with track functions, the R&S RTA4000 provides several pre-configured
signals with track waveforms. These example waveforms require option R&S RTA-B6.
To display an example signal:
1.
Press the
[Apps Selection] key.
2. Select the "Track" tab.
3. Select the signal.
4. Connect the input channels. The required connection is shown in the upper left cor-
ner of the display.

PWM Unipolar "Gen" generator output "Ch1"
PWM Bipolar "Gen" generator output "Ch1"
PDM Unipolar "Gen" generator output "Ch1"
PDM Bipolar "Gen" generator output "Ch1"
Inverter "Gen" generator output "Ch1"
DC Motor "Gen" generator output "Ch1"
3 Phase Motor Pattern Generator: P0, P1, P2 "Ch1", "Ch2", "Ch3"
PWM - RGB LED Pattern Generator: P0, P1, P2 "Ch1", "Ch2", "Ch3"
The track of the bipolar inverter signal shows the real sinus waveform, which considers
the double pulse arising from the inversion. This sinus track can be compared with the
ideal control signal.
