O perational Information
Calibrated Sweep Rates Five microseconds to one second/division
in 17 steps.
Steps in 1-2-5 sequence. Each sweep rate
can be increased 10 times with X 1 0 mag­
nifier. Extends fastest sweep rate to 0.5
microsecond/division.
Unmagnified Time Measurement
Accuracy (over center eight di­
visions of graticule)
5/cs to 0.2 s/DIV Within 3%.
VARIABLE TIME/DIV control set to CAL.
0.5 s to 1 s/DIV
Within 4%.
Magnified Time Measurment Ac­
curacy (over center eight di­
visions of graticule, equivalent
magnified sweep rates given)
2 microseconds to 20 millisec-
onds/division
Within 4%.
VARIABLE TIME/DIV control set to CAL.
Exclude first two and last two divisions of
total magnified sweep length at 0.5 and 1
microsecond/division.
0.5 and 1 microsecond, 50
milliseconds and 0.1 sec-
ond/division
Within 5%.
Uncalibrated (variable)
Sweep Rates
Provides continuously variable sweep rates
between the calibrated steps. Extends slow­
est uncalibrated sweep rate to at least
2.5 seconds/division.
Normal/Magnified Registration ± 1 division, or less, horizontal trace shift
when switching from normal to magnified
sweep. Internally adjustable.
Sweep Length
10.5 to 11 divisions. Internally adjustable.
