This example shows you how to configure the equipment and Signal Studio software to monitor a DVB-T/H format video. A similar procedure can also be used for other formats.
Click
from the menu.In the Waveform Setup (
) pane: click .Edit the parameters to set up a waveform.
Set the
to and select as the video type.
Click the Instrument Settings node in the tree view, set the MXG/EXG/ESG/PSG’s frequency and amplitude to the values below
Frequency: 474 MHz
Amplitude: -50 dBm
Click
Generate Waveform button in the tool bar. The software generates an
I/Q waveform file in accordance with the current waveform configuration
and signal generation setup. Waveform generation time varies proportionally
to the complexity of the waveform.
After the waveform is generated, you can examine its characteristics.
View the CCDF plot for the carrier based on the configuration by clicking the carrier in the tree view. For more information, refer to CCDF Plot.
By clicking Waveform Setup in the tree view, you can view plots of the baseband spectrum, I and Q signals, and CCDF curve prior to downloading the file to the signal generator. For more information, refer to CCDF plot and waveform plot.
To
download the waveform file to the signal generator, click Download
in the tool bar if you have configured the instrument connection. The
signal generator automatically begins to play the digital video waveform.
The waveform file, however, cannot be modified after downloading it to
the signal generator.
You can observe the color bar display on a DVB-T/H receiver as shown in the figure below.
