  • All-In-One : This instrument features the signal generator capability and BER measurement capability in a single package. The BER function is used to measure the front-end section, the MPEG2-TS function is used to visually check entire system. In addition to the digital terrestrial TV broadcasting, this instrument can also be used for the connected segment transmission of 1, 3, and 8 segments in digital terrestrial audio broadcasting.
  • Arbitrary Transmission Parameter Settings : The transmission parameter can be arbitrary set via the front panel controls. The QVGA LCD graphically displays the setting conditions.
  • MPEG2-TS Encoding/Modulation In Realtime : The MPEG2-TS applied from the DVB-ASI or DVBSPI connector can be encoded/modulated in realtime. In addition to the MPEG2-TS, broadcasting TS prescribed in the ARIB standards can also be used.
  • 100 Preset Conditions : Up to 100 preset conditions can be stored in the memory. Since the stored contents can be categorized into 10 groups, the preset mode is convenient for inspection applications.
  • Various Factory Options :
    ㆍ OP71 Moving Picture Option – By installing a HDD with USB connector, a stream including HDTV content (i.e., requires large storage area) and long-time TS can be played back from the HDD.

    ㆍ OP72 Fading Option – The fading noise can be added to a mobile and portable receivers to check a ghost and multipass.

OP70: 동영상 Option
  HDD와 DVD-ROM를 장착 하는 것으로, 대용량의 보존 Area가 필요한 HDTV Contents를 포함한 Stream이나
장시간의 TS를, HDD로부터 재생할 수가 있습니다.
 
OP72: Phasing Option
  이동기기나 휴대수신기에서 특히 과제가 되는 Ghost나 Multi Pass등이라고 하는 Phasing Noise를 부가 할 수
가 있습니다.
