Detailed Product Description: | DS7618 series is a German power company for the digital set-top box integrated development of the automated test system. DS7618 products, highly integrated, powerful, able to automate the production testing, is the best set-top box manufacturing test solution. ? set-top box unit source Enter the desired RF signal generation set-top boxes. Stream flow generator standard test TS, TS ASI input streams through the RF modulator, set-top boxes based on different testing requirements, optional RF modulator for the DVB-C/T/S, ATSC or GB20600 standard modules, RF modulator The corresponding standard radio frequency signal; interference signal generator produces a variety of interference. Including the white noise, co-channel interference, interference interference attenuator range of precise control; interference and radio frequency combiner generator produces RF test signal into the set-top boxes. Video and audio analysis module Tested set-top box to receive analog video and audio signals, analysis of video and audio signal indicators; output video and audio signals, sent to monitor and headphones. ? Master system Automatic control signal source set-top box unit, video and audio analysis module and the measured set-top box, a device that can automatically set-top boxes all tests. The test system is a set-top boxes for digital set-top box manufacturers to develop automated production integration testing device can complete a variety of standard test signals and video and audio analog output of the test. The device has the following characteristics: 1. Comply with the relevant national testing standards set-top boxes, such as GD / J 12-2007 "users to receive digital cable television system decoder (STB) technical requirements and methods of measurement" for their support. 2. All-WINDOWS interface to realize the digital set-top box video output (including composite, YUV component) and audio output (LR channel) Automatic Measurement of the indicators. Users can customize many sets of automatic measurement program. Support user-defined limits to determine compliance, the results show intuitive, with a very clear distinction between color measurement results of the qualified or not, making measurements easy and fast. 3. Application of customer-defined testing program, the operator without the complexity of the operation, simply press a button or point a mouse, DS7618 can automatically complete all the required testing of the user, and in the testing process automatically switches to the the required video and audio signals. Greatly simplifies testing, speed up the testing speed. 4. The system also supports printing and saving of measurement results can be generated automatically print the report, can be very convenient for large quantities of statistics and analysis of test results, easy to manufacturers control product quality, improve product quality. 5. The test system can automatically control the set-top box standard TS stream output bit rate, modulation and RF modulation frequency, amplitude, C / N and a variety of band interference, and to achieve full automation of the testing process. 6. The system TS stream play module, RF signal control module, the signal modulation module and a video and audio test module integrated on a single host, makes the system common test system needs to be completed by 4 to 5 devices to complete the work . Has a very high integration and cost-effective, is the set-top box manufacturers is the ideal choice. 7. The system except for the measurement of production, but also to provide a rich R & D interface features. Users can simply operate with the mouse or keyboard to view the details of the waveform and values, you can view the details of some indicators of measurement, you can also enlarge the local to check any specific test points, to maximize R & D personnel to meet the needs of test and analysis, and retained some of the functions of production testing, test results can still use the user specific set of colors to distinguish the result was qualified or not.
