Time Base Accuracy, Magnify Off The limits are as follows:
Conditions Time Measurement Accuracy
+15_ Cto+35_C ±2%.
-10_ Cto+15_C and
+35_ Cto+55_C
±3%.
Sweep accuracy applies over the center eight divisions. Excludes
the greater of either the first

division or 25 ns from the sweep start
of the magnified sweep and anything beyond the 100th magnified
division.

division or 25 ns from the sweep start
of the magnified sweep and anything beyond the 100th magnified
division.
Horizontal Position Control Range The position control is able to move the start of the sweep to the
right of the center vertical graticule and able to move a time mark
corresponding to the tenth division on an unmagnified sweep to the
left of the graticule center.
Variable Control Range Continuously variable between calibrated seconds/division settings.
Extends both the Main and Delayed sweep seconds/division setĆ
tings by a factor of 2.5 times.
Delay Accuracy, Main Sweep Trigger
Point to Start of Delayed Sweep
±(0.5% of reading + 5% of 1 division of the Main sweep + 25 ns).
Delta Delay Accuracy ±(0.5% of reading + 5% of 1 division of the Main sweep + 10 ns).
