HORIZONTAL DEFLECTION SYSTEM (cont)
Sweep Linearity
(relative to center two
displayed divisions)
± 5%.
Sweep Linearity applies over the center eight
divisions. Excludes the first 1/4 division or
25 ns from the start of the magnified sweep
and anything beyond the 100th magnified
division.
POSITION Control Range
Normal Displays
Able to move the start of the sweep to the
right of the center vertical graticule; able
to move a time mark corresponding to the
end of the tenth division of an unmagnified
sweep to the left of the center graticule.
X-Y Displays
At least +13 divisions.3
XI0 Magnifier Expands the normal sweep by ten times around
that portion of the sweep positioned at the
center vertical graticule line.3
Registration
(X10 to XI)
0.5 division or less shift.
Variable Control Range Continuously variable between calibrated
SEC/DIV settings. Extends both the A and B
sweep time per division by at least a factor
of 2.5.
Sweep Length Greater than 10 divisions.
Delay Time
Delay Control Range
Less than 0.1 division to 10 times the A
SEC/DIV switch setting. Maximum value does
not exceed end of the A Sweep.
Jitter 1 part in 20,000, or less, peak-to-peak,
during a two-second time interval.
Delta Time
Delta Control Range 0 to greater than 9.9 divisions to the right
of setting of DELAY control, but maximum
value does not exceed end of the A Sweep.
