Leader LG3802S1-1
ISDB-T Signal Generator
Discontinued

  • 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 MPEG-2 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.
  • MPEG-2 TS encoding/modulation in realtime
    The MPEG-2 TS applied from the DVB-ASI or DVB-SPI connector can be encoded/modulated in realtime. In addition to the MPEG-2 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.

The LG 3802 (S1 version) ISDB-T Signal Generator with the OFDM capability conforms to Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) standards for digital terrestrial TV system in Japan. This instrument features a channel coding/modulation, C/N generator, and up converter in a single package.

Consequently, the modulated signal covering VHF and UHF channels can be output. Since a pseudo random signal source (PN) and BER counter are provided, the BER measurement of a TV set and tuner can be performed with this model only. In addition to the internal TS signal, the MPEG-2 TS can be externally applied. Therefore, the receiver can be checked visually and acoustically by using the existing TS. With such versatile capabilities, overall functions of the reception system can be tested.
