CHARACTERISTICS PERFORMANCE REQUIREMENTS
VERTICAL DEFLECTION SYSTEM — ALL CHANNELS
Bandwidth Limit
(-3 dB bandwidth)
20 MHz ±15%.
Low Frequency Linearity
(Relative to
center screen)
Within ±5%.
Linearity is measured by positioning a two-
division test signal anywhere on screen and
noting the amplitude change.
TRACE SEP Control
Position Range
At least ±4 divisions.
CHOP Mode Clock Rate 625 kHz ±10%.a
Delay Match (CH 1 or CH 2
to CH 3 or CH 4)
Less than 200 ps difference.
HORIZONTAL DEFLECTION SYSTEM
Sweep Range
A Sweep
0.5 s/div to 20 ns/div in a 1-2-5 sequence.3
XI0 magnifier extends maximum sweep speed
to 2 ns/div.
B Sweep
5.0 ms/div to 20 ns/div in a 1-2-5 sequence.3
XI0 magnifier extends maximum sweep speed
to 2 ns/div.
Accuracy
15° C to 35°C
Unmagnified Magnified
+ 2% + 3%
-10°C to 15°C
and 35 °C to 55°C
± 3% ± 4%
Sweep Accuracy 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.
