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.
