2. SPECIFICATIONS
2.1 Description
The LG 3803 8VSB/QAM Signal Generator, conforms to 8VSB (digital terrestrial TV in
USA System) and 64QAM/256QAM (CATV) standards, 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.
Providing pseudo random signal (PN) and BER counter can perform BER measurement of
receivers and tuners with a signal unit.
In addition to the internal TS signal, the external MPEG-2 TS can be used to evaluate
video, and sound quality. Such powerful features are ideal for total evaluation of a
reception system.
2.2 Features
• 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 broadcasting 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 CATV. Such features are ideal for the production line of STB and tuners.
• Arbitrary modulation system settings
The modulation system can be arbitrary set via the front panel controls. The QVGA
LCD graphically displays the setting conditions.
• Encoding/modulation MPEG-2 TS 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.
• Various options
• LG 3803-OP70 Moving Picture Option (Factory option)
With the HDD and DVD-ROM installed, a stream including HDTV content (i.e.,
requires large storage area) and long-time TS can be played back from the HDD.
• The BER measurement of Out Of Band in CATV systems can be performed by
connecting the LG 3803-01 Out Of Band Generator (sold separately).
