Feature
  • 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. Also, such features are ideal for the production line of STB and tuners.

  • 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.

  • 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.

Option
  • OP 71: USB STORAGE Option (factory option)

    The TS can be played back from the HDD drive connected via the USB, or internal HDD drive.

  • OP 72: Fading Option (factory option)

    The fading noise can be added to a mobile and portable receivers to check a ghost and multipath.

  • OP 73: USB STORAGE Option (factory option)

    This add-in software adds the DVB-H capability to the Model LG 3804

  • OP 74: Fading Option (factory option)

    This add-in software adds the DVB-C capability to the Model LG 3804.

Applications
Designed to address the challenges of DTV tuner testing, the LG 3804 provides all of the signal control necessary for testing the performance of DVB-T compliant tuners and receivers. 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. This basic model can expand applicable capabilities to DVB-C and DVB-H with various Options.
