模擬信號發(fā)生器介紹

模擬信號發(fā)生器K-8278A是測試Display Device的綜合影像信號發(fā)生器。K-8278 可以支援多種類的標準信號, 例如，LCD TV/Monitor, PDP TV, 投影儀等。它可以支援 HDMI 4ports, Display 1port 等多種 Multi ports ，適用于各種生產(chǎn)線。K-8278A 獲得了標準HDMI, DisplayPort 的認證，提升了產(chǎn)品可靠性。
- 點頻寬帶
    可以支援高解像力的 Timing，并采用了Analog 330MHz / DVI Dual Link 330MHz / DisplayPort 300MHz 出口端式樣。
- Multi Ports Output
  HDMI 4ports, DisplayPort 1port等可以支援 Multi Ports 的出口端，可以同時測試多種 Display Device。
  特別適用于 CELL-LINE 生產(chǎn)線。
- HDMI V1.4 功能
  采用了 HDMI V1.4 Standard 功能，可以測試 3D Format / Audio Return Channel / Ethernet / CEC /  Deep Color 功能。
- 多種信號出口端，可以測試 3D 功能
    HDMI V1.4 出口端外 Analog, DVI, DisplayPort, D-TV 出口端可以測試 3D
- 采用 DisplayPort V1.1a 功能
    采用了DisplayPort V1.1a Standard 功能，Lane count / Pre-emphasis / Swing level / DPCD / SSC 等，可以支援各種測試。
- TV/D-TV 標準信號出口端
    TV 出口端采用了 NTSC, PAL, SECAM的 Standard specification，SMPTE 及 ITU 標準規(guī)格，并對 etext, V-Chip, Closed Caption 功能可以進行測試。
- 采用 Multi Media Play 功能
    可以實現(xiàn)多種解像力檢測及 Source file 出口端檢測，可以支持 Video format (wmv, avi, mpg, vob, mp4, asf, tp, trp), Audio format(MP3, WMA, AAC, Ogg, PCM) 和 Image (BMP, JPG)。
