3 Technical indicators

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 power;

                                                            Figure 1

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.
