GENERAL SAFETY SUMMARY  
Review the following safety precautions to avoid operator's injury and loss of life and prevent  
damage and deterioration to this instrument. To avoid potential hazards, use this product as  
specified.  
WARNING  
Warnings on the Cases and Panels of the Instrument  
Operator should not remove any cases or panel for any reasons. If you touch inside the  
instrument it could result personal shock or fire hazard. Refrain from spilling any liquid  
on or inserting anything flammables or piece of metal into the ventilation of the instrument.  
Such actions could cause fire, shock, malfunction and be an accident hazard while the  
power is on.  
Warnings on Power Line  
Make sure to connect only to the rated power line voltage. Excess voltage may  
cause fire.  
Confirm the voltage of the commercial power line before connecting the AC power  
cord. The power frequency of the power line should be 50/60 Hz.  
Warning on the Power Cord  
Use only the optional power cord that is attached to this instrument. The use of the  
power cord other than that attached could cause fire hazard.  
If the attached cord is damaged stop using it and contact your local Leader agent.  
Should you use a damaged cord, it could cause a shock or create a fire hazard. When  
you pull out the cord be sure to hold it by plug and pull from the socket not by holding  
the cord wire.  
Warning on Fuse  
When the fuse is melted the instrument stops operation. If the fuse melted, turn off the  
power switch and disconnect the power plug from the socket. If you change the fuse  
while the cord is connected to the socket, it could cause a shock hazard. Only use the  
specified type and rated current and voltage fuses.  
If the cause for melting fuse is unclear or if you suspect there is damage to the instrument  
or if you have no proper fuse at hand please contact your local Leader agent.

do so could cause fire, shock, malfunction and create a dangerous accident hazard.  
Warning while Operating  
While operating the instrument in smoke, fire, or a bad smell, occurs, turn off the  
instrument at once for it could cause a fire hazard. When such a case occurs, turn off the  
power switch and pull the plug of the cord from the plug socket. Contact your local Leader  
agent after confirming there is no fire.  
Warning about Ground  
The instrument has a ground terminal to avoid electric shock hazard and to protect the  
instrument from damage. Ensure that the product is properly grounded for safe operation.

GENERAL SAFETY SUMMARY  
CAUTION  
Caution on Input/Output Terminals  
Input Terminals are rated with a maximum input. Do not supply an input over the specified  
rating in the standard section of the instruction manual. Also, do not supply external  
power to Output terminal, this could cause the instrument to malfunction.  
Caution when Not to Using Instrument the for a Long Time  
Make sure to disconnect the power cord from the socket when you do not use the  
instrument for a long time.  
Calibration  
This instrument is produced under the strictest quality controls at the factory, but  
accuracy may gradually deteriorate due to worn components.  
Therefore, periodic calibration should be performed.  
When service or calibration is required, contact your local Leader agent.  
Routine Maintenance  
Remove the power cord plug from the socket when cleaning the instrument.  
Avoid the use of thinner or benzene solvents for cleaning cases, panels and knobs since  
this might remove the paint or damage plastic surfaces.  
Wipe cases, panels, and knobs lightly with a soft cloth damped with neutral detergent.  
Do not allow water, detergent, or other foreign objects to enter the instrument while  
cleaning.  
If a liquid or metal object enters the instrument, it can cause electric shock or fire.  
Please conform to the above warnings and cautions for safe operation. There are cautions in  
each area of in this instruction manual, so please conform to each caution. If you have any  
questions about this manual, please feel free to contact your local Leader agent.

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 systenckage.
