Description
Designed to address the challenges of DTV tuner
testing, the LG 3803(S1 version) provides all of the
signal control necessary for testing the performance
of ATSC compliant tuners and receivers.
The RF output can be set to emulate 8VSB, 64 and
256QAM modulation formats and the modulation frequency
can be set from 50 MHz to 900 MHz covering
the entire VHF and UHF spectrum. Output level ranges
from -100 to +13 dBm (50 Ohm) and it is settable
with 0.1dB resolution; ideal for doing input sensitivity
tests.
A pseudo-random (PN) generator and a BER counter
are built into the instrument and facilitate easy BER
measurements in a single unit.
The instrument can be modulated internally (3 built in
test patterns; color bars and monoscope) or can be
externally modulated (DVB-ASI or SPI input).
The QVGA display provides easy instrument control.
The instrument can be Ethernet controlled. Remote
control allows preset recall and increment; up to 100
presets can be set up and recalled aiding in the automatic
testing process.
