FEATURES
NTSC COLOR BARS
SELECTABLE COLOR
CONVERGENCE PATTERNS
BLACK RASTER
CRYSTAL OSCILLATORS
COMPOSITE VIDEO OUTPUT
Generates standard NTSC color bars pattern (eight bars of
standard EIA colors) at NTSC prescribed luminance and
chrominance levels and phase.
Color can be switched on or off.
Dots, crosshatch, center dot, and center cross patterns for
static and dynamic convergence.
Provides sync and reference black for a clear blemish-free
raster.
IF, CH 3, CH 4. 30Hz. and sync generation are crystal-
controlled for frequency accuracy and stability.
Composite video output with variable 0 to ± 1V p-p amplitude
into standard 75Ω impedance. Calibrated 1V p-p with
negative
sync.

30Hz OUTPUT
4.5MHz SOUND SUB-CARRIER
Standard 75Ω output modulated by composite video at
10mV rms on channel 3, channel 4, or 45.75MHz i-f.
All outputs can be used simultaneously for maximum
flexibility. Permits more complementary testing or
multiple independent usage of instrument.
Digital red, green and blue (RGB) signals for computer and
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 TTL output is useful for video recorder applications.
4.5MHz subcarrier modulated with 1KHz audio tone can be
switched on to check sound and verify picture and sound
isolation.
