A
Sweep:
from

second/division
to
0.05
microsecond/division
in
22
steps
in
a 1-2-5
sequence.

from
50
milliseconds/division

Calibrated Sweep Accuracy
Unmagnified sweep
accuracy
is
±2%
from
+20°C
to
+30° C ( +68° F
to
+86°
F)
and
±3%
from
-15°
C
to
+20°C
and
+30°C
to
+55°C
(+5°F
to
+68°F
and
+86°F
to
+131°F).
For
the
same
temperature
ranges, magnified
sweep
accuracy
is
±3%
and
±4% respectively. Exclude
the
first
and
last
50
ns
of
the
5 ns,
10
ns,
and
20
ns
magnified sweep rates.

ten
divisions unless
otherwise
specified.
1-2
Sweep
accuracy,
over
any
two

less division portion
of
the
sweep,
is
±5%. Exclude
the
first
and
last magnified
divisions of
the
5 ns
and
1 O ns/div magnified sweep
rates. Also
exclude
the
first
and
last
50
ns
of
the
5,
10,
and 20 ns/div magnified sweep rates.
Mixed sweep
accuracy
is
2%
plus
the
measured A sweep
error
when
viewing
the
A
sweep
portion
only.
The B
sweep
portion
retains its
normal
accuracy.
A Time/Division Variable
Range
Provides
continuously
variable (uncalibrated) sweep
rates
between
the
calibrated
settings
of
the
A TIME/DIV
switch.
Extends
the
slowest
A

to
at
least 1.25

by
at
least a
factor
of
10.
