LCG-412B Handheld NTSC Pattern Generator
Small enough to slip into a coat pocket, briefcase or toolbox, the LCG-412B is the ideal video pattern generator for field ser-
vice of TVs, VCRs and monitors. It features baseband video output that handles the standard 75 ohm load and provides
Full- Field 75%, Color Bars, Crosshatch, Dots, a Corner Marker and White, Red, Green or Blue Full-Field rasters. These
signals are also modulated on VHF or UHF carriers with 1 kHz internal sound modulation. Full broadcast coverage is pro-
vided with a slide rule dial for channel indication. Runs on six AA cells or an AC adapter,.
Video Sweep Generator with Multiburst
The 430 supplies Sweep and Multiburst signals, as well as
SMPTE and Full Field Color Bars and Flat Field rasters
in eight colors, including B&W. The Field Rate Sweep
features start-stop control to tailor Sweep width to the
band of interest. Five separate sets of precision dropout
markers spot key frequencies, and each set can be used alone or in combination with the others. Both Sweep and
Multiburst are continuously variable, independent of Sync Amplitude, but a separate control sets overall output
level. For Sweep/Multiburst operations where sync is not desired (preamp checks), sync may be switched off.
Here the scope is triggered from V or H drive signals or composite sync for WFM monitors.
■ Start-Stop Sweep to 10 MHz
■ 5 Sets of Sweep Markers
■ Sweep and Multiburst
■ Sweep with and without composite sync
■ Y/C operation
■ Sweep Amplitude Continuously Variable
408/408NPS
NTSC • NTSC/PAL/SECAM Test Generators
MicroProcessor control and digital synthesis give the 408 extreme flexibility in test signal
programming of both video and RF outputs. Signals available simultaneously include com-
posite video, Y/C, Y/R-Y/B-Y, RGB, Full Sync Generator outputs, Audio Test tones (400
Hz and 1 kHz) and modulated output from 30 to 900 MHz. Multiple test patterns
include Wide and Narrow Video Sweeps and Multiburst with last burst variable to 15
MHz. Signal modifiers include Polarity Inversion, Superimposed Circle and Moving
Marker, as well as On/Off and Level control of Burst, Sync, Setup, Luminance, Chroma, R, B and G. Genlock
and remote control are standard. GPIB is available as an option. Applicable video and audio modulation is select-
ed by system designation. The FUNCTION DATA block provides easy access to all programming functions.
Here, up to 100 test setups can be stored, each one holding front panel settings (Pattern Selected, Genlock
On/Off, Signal Modifiers, etc.), tailored or standard video parameters. RF channel are selected or tailored to any
carrier frequency between 30 and 900 MHz. Program control over video parameters allow component values for
Betacam to be set up. The LCD panel shows partial programming menus, but the full menus may be superim-
posed on the selected pattern on a monitor screen.

The 408NPS operates in the NTSC system plus it extends all operating features into PAL (PAL-B, C, D, G, H, I, K and L)
and SECAM (SECAM III-B, D, G, H, K and L).
