Ideal For The Production, Test and Alignment Of ATSC Compliant Tuners And Receivers/STBs.
GENERAL
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 +13dBm (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.
