MDW1698 HDTV BER tester
- Product Details
- Company Profile
◆ Equipped with LCD display, real-time visual display of the current MPEG stream error state ◆ DTV broadcast transmission system dedicated to the 23-order pseudo-random code test function ◆ error monitoring range (10-2 - 10-11) ◆ BER test is per-bit (
◆ test file
Test file for the 15 bands to 23 bands either pseudo-random code sequence, and the data packet form (188 bytes per packet) for the first byteof 0X47
, Followed by 187 bytes of pseudo-random code; or the provisions of the first four bytes according to MPEG2, followed by 184 bytes of pseudo-random code.
Test building process from the pseudo-random code sequence of any byte,so that the process of establishing the test fast, does not require users to wait.
◆ image files
For a variety of standard image file, multiple bit rate of HDTV and SDTVimages of TS stream activities.
◆ Output Interface
☆ DVB ASI and SPI standard BNC socket standard D-25 Block of a hole.
Parallel data format: 188/204/208 bytes per packet
Serial data format: 188 bytes per packet
☆ internal clock rate: from 8 Mbps to 80 Mbps can be set, changing theminimum amount of 1bps
External clock rate: determined by the external clock.
☆ internal clock accuracy: error of less than ± 20/10/3/1 ppm (depending onthe accuracy of internal 27 MHz crystal).
(Please choose one according to your requirements value)
☆ External Clock Specifications
ASI at: bit clock (same bit rate, physical interface BNC; TTL level, 50W)
