1Video in and Audio in interfaces
The video input and audio input interfaces of the analog television
modulation module, are respectively connected to the Video in
interface to the Y/CVBS interface and Audio in to the L or R
Analog TV RF modulated signal output interface with right side
interface with 30dB attenuation.
3Y/CVBS, Pb, Pr interface
Analog TV composite signal and color difference component signal
output interface, in which the Y/CVBS interface outputs a composite
signal (CVBS) when the signal format is PAL and NTSC, and outputs a
luminance signal (Y) in the color difference signal under other
4L, R, AES/EBU interfaces
Audio output interface, where L and R are analog audio output
interfaces, and AES/EBU is a digital audio output interface.
5SDI interface and HDMI interface
Digital video signal output interface.
Digital TV RF modulated signal output interface.
7System Peripheral Interface
It is convenient for users to connect external devices such as
monitors, mouse, keyboards, and USB flash drives.
8System power interface and switch
Connect and control system power.

TV energy efficiency test
1. Connect the "Y/CVBS" connector on the rear panel of the RDL-320
to "Vdieo in", "L" or "R" to "Audio in", and the right side of the
"RF-ATV" analog TV RF connector. The interface with "-30dB" is
connected to the antenna input interface of the TV under test with
a BNC cable and an adapter;
2. Open the desktop shortcut "TIRT", the interface is shown in figure 1, in the "signal list" choose
"SD_ static. MPG", "video formats" choose PAL, then click the
"play" button, the broadcast signal, according to the standard
adjustment eight gray-scale of the television, and test the static
3. After the static standby power test is completed, click the
"Stop" button to stop playing the signal, switch the signal to
"SD_dynamic.mpg", and test the dynamic power;
4. Connect the "RF-DTV" interface on the rear panel of the RDL-320
to the antenna input interface of the TV under test using the BNC
cable and adapter;
5. Open the desktop shortcut "StreamXpress", the interface is shown in Figure 2. Click "RF Output Control" in
the "Settings" menu to enter the output level setting interface. As
shown in Figure 3, set the output level to -60dBm and set the
modulation parameters according to Figure 2 , the signal to be
measured select D: signal TS energy efficiency HD static. ts,
click, "play" button, test the static power, test signal is
switched to HD dynamic. ts, and play, test Dynamic power.
6. The test of the set-top box is similar to the digital part of
the TV. The "RF-DTV" interface on the back panel of the RDL-320 is
connected to the antenna input interface of the set-top box under
test using a BNC cable and an adapter.Select the corresponding
digital TV input format according to the set-top box format. If it
is a DVB-C standard set-top box, set the modulation parameter in
“StreamXpress” to DVB-C, 64QAM,
Set "Sym" to "6875000", as shown in Figure 4. If the set-top box is
a DTMB standard set-top box, set the modulation parameters
according to Figure 2.
Monitor energy efficiency test
1. Connect the VGA, DVI, and DP ports of the RDL-320 rear panel to
the corresponding input of the monitor as shown in Figure 1. If the
monitor is an HDMI port, use a DP-HDMI adapter to convert to a HDMI
cable,the connect with monitor.

from the drop-down menu, as shown in Figure 2;
3 in the "multi-monitor (M)" menu, select "Copy desktop on 1 and
2," as shown in Figure 3
4. In the "multi-monitor (M)" menu, select "display only on the
desktop 2", as shown in Figure 4, click "OK", and in the pop-up
dialog box, click "keep changes", then RDL-320 host display The
screen turns black and the system desktop is displayed on the
monitor under test;
Then right-click on the desktop, select "Screen Resolution (C)" in
the drop-down menu and select the desired resolution in the
"Resolution Menu". Finally, click OK, and click "Keep Changes" in
the pop-up dialog box.
5. Enter the "Computer Monitor Test Signal" folder in the D drive
directory (if the monitor is a widescreen (16:9 or 16:10), select a
1920x1080 resolution test pattern. If it is 4:3, select 1024. ×768
resolution test chart), open the picture that needs to be played,
and click "Play slide (F11)", as shown in Figure 5;
6. Right-click on the full-screen playback picture, select "Pause"
in the drop-down menu, as shown in Figure 6, start the test.
