Information
Performance
Requirements
Vector Display
Differential Phase ≤1_.
Differential Gain ≤1%.
Measured with 140 IRE
(1 V) linearity signal with 40
IRE (300 mV) of subcarrier.
Position Control Range
Horizontal ≥1/4I (6 mm) from center.
Vertical ≥1/4I (6 mm) from center.
Clamp Stability 1/64I (0.4 mm) or less. Center Spot movement
with Rotation of PHASE
control.
Variable GAIN Range +14 dB to –6 dB of 75% color
bar preset gain. Unterminated color bar
signal can be brought to
appropriate targets. Burst
from a triple-terminated
signal can be moved to the
compass rose.
Max Gain >X5.
Variable GAIN Phase
Shift ±1_ as gain is varied from
+3 dB to –6 dB.
