A TRIGGER (NORM)
INT Can be set to any point of the trace
that can be displayed.8
EXT. DC
At least ±1.6 V, 3.2 V p-p.
EXT, DC -r 10
At least ±16 V, 32 V p-p.8

VAR HOLDOFF Control
Increases A Sweep holdoff time by at
least a factor of 10.8
HORIZONTAL DEFLECTION SYSTEM
Sweep Rate
0.5 s per division to 0.05 ms per
division in a 1-2-5 sequence. X I0
magnifier extends maximum sweep
speed to 5 ns per division.
Accuracy
Unmagnified Magnified Sweep accuracy applies over the
+ 15°C to +35°C
±3% ±4%
center 8 divisions. Exclude the first
25 ns of the sweep for magnified
sweep speeds and anything beyond
the 100th magnified division.
0°C to +50°C
± 4%a
±5%8
POSITION Control Range
Start of sweep to 10th division in XI or
100th divisions in X I0 will position past
the center vertical graticule line.
Sweep Linearity
±7%.
Linearity measured over any 2 of the
center 8 divisions. With magnifier in X I0,
exclude the first 25 ns and anything past
the 100th division.
Variable Control Range
Continuously variable between
calibrated settings. Extends the A and
B sweep speeds by at least a factor of
2.5.
Delay Time
Applies to 0.5 ms per division and
slower.
Delay time is functional but not calibrated
at sweep settings above 0.5 ms per
division.
Dial Control Range
<0.5 + 300 ns to >10 divisions.
Jitter
One part or less in 20,000 (0.005%) of
the maximum available delay time.
