GENERAL
FEATURES
LG 226
TV SIGNAL GENERATOR
The LG 226 TV Signal Generator provides the capabil-
ity to modulate an analog TV signal in VSB-AM format
applicable to the PAL, NTSC, and SECAM broadcast-
ing systems.
The TV signals of VHF, UHF, and CATV channels can
be generated by applying the external composite
video signal and audio signal.
The full-field color bars and line sweep signals, and 1
kHz/400 Hz audio signals can also be generated.
This instrument can also be used as an analog TV
signal modulator of the LT 450 Video Signal Genera-
tor since this instrument provides the LT 450 control
capability.
■
Usage
Suitable to check the video and sound of analog TV.
■
RF output frequency
The RF frequency can be set from 30 MHz to 950
MHz in 50 kHz steps.
The channel table is provided to set the RF signal in
channel instead of the frequency.
■
Output attenuator
Highly reliable electronic attenuator is used.
■
Video modulation
The VSB (Vestigial Sideband) modulation is used to
eliminate the interference to of adjacent channels.
■
Sound modulation
Applicable to both FM modulation and AM modula-
tion (L method).
■
Preset function
Up to 100 front panel settings can be stored and re-
called.
■
Remote control function
The preset conditions stored in the preset memory
can be selected by specifying the address in INC,
DEC, and RESET operation via the REMOTE control
connector.
■
GPIB function
All front panel keys except the POWER switch can
be remotely controlled since the GPIB interface (con-
forming to IEEE488.1) is provided as standard.
