Generates standard NTSC color bars pattern (eight bars of
standard EIA colors) at NTSC prescribed luminance and
chrominance levels and phase.
SELECTABLE COLOR

CONVERGENCE PATTERNS
Dots, crosshatch, center dot, and center cross patterns for
static and dynamic convergence.
BLACK RASTER
Provides sync and reference black for a clear blemish-free
raster.
CRYSTAL OSCILLATORS
COMPOSITE VIDEO OUTPUT
Composite video output with variable 0 to ± 1V p-p amplitude
into standard 75
Ω impedance. Calibrated 1
V p-p with
negative sync.
RF OUTPUT
Standard 75
Ω
output modulated by composite video at
10mV rms on channel 3, channel 4, or 45.75MHz i-f.
SYNC PULSE OUTPUTS
All outputs can be used simultaneously for maximum
flexibility. Permits more complementary testing or
multiple independent usage of instrument.
RGB OUTPUTS

video monitors with standard 525 line, 15.750KHz scan. D-
Type sub-miniature connector provides red, green, blue,
horizontal sync, and vertical sync signals and is IBM Model
5153 PC monitor compatible. Output level is switch
selectable between TTL and LOW ( 0 . 8 ± 0 . 2 V ) .
30Hz OUTPUT
30Hz TTL output is useful for video recorder applications.
4.5MHz SOUND SUB-CARRIER
4.5MHz subcarrier modulated with 1KHz audio tone can be
switched on to check sound and verify picture and sound
isolation.
