0.5 s/div to 20 ns/div in a 1-2-5 sequence.
X10 magnifier extends maximum sweep speed to 2 ns/div.
5.0 ms/div to 20 ns/div in a 1-2-5 sequence.
X10 magnifier extends maximum sweep speed to 2 nsidiv
Unmagnified Magnified
+2% +3%
+3% +4%
Sweep Accuracy applies over the center eight divisions. Excludes
the greater of the first 1/4 division or 25 ns from the sweep start
of the magnified sweep and anything beyond the 100th magnified
division.
+5%.
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.
At least +13 divisions.
Expands the normal sweep by ten times around that portion of
the sweep positioned at the center vertical graticule line.
0.5 division or less shift.
Continuously variable between calibrated SEC/DIV switch set-
tings. Extends both the A and B sweep time per division by at
least a factor of 2.5.
Greater than 10 divisions.
Less than 0.1 division to 10 times the A SEC/DIV switch setting.
Maximum value does not exceed end of the A Sweep.
1 part in 20,000, or less, peak-to-peak, during a two-second time
interval.
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.
