(2) Rotate oscilloscope calibrator EDIT FIELD knob for an err display of 0.0%.
Adjust R132 (fig. 1) for 5 divisions of vertical deflection (R).
10. Timing
a. Performance Check
(1) Set oscilloscope calibrator MARKER output to 1 ms.
(2) Set TI vertical VARIABLE control as needed to view 2 to 4 divisions of display.
(3) Using horizontal POS control and oscilloscope calibrator EDIT FIELD knob,
align 1 time marker per division from the second to the tenth vertical graticule line. If
oscilloscope calibrator err display readout does not indicate within 5%, perform b (1)
below.
(4) Press and release ms pushbutton to s /div.
(5) Set oscilloscope calibrator MARKER output to 1 s.
(6) Using horizontal POS control and rotating oscilloscope calibrator EDIT FIELD
knob, align 1 time marker per division from the second to the tenth vertical graticule line.
Oscilloscope calibrator err display readout indication will be within 5%.
(7) Pull horizontal VARIABLE control out to X5 and set oscilloscope calibrator
output for 0.2 s.
(8) Using horizontal POS control and rotating oscilloscope calibrator EDIT FIELD
knob, align 1 time marker per division from the second to the tenth vertical graticule line.
If oscilloscope calibrator err display readout indication does not indicate within 5%,
perform b (2) below.
(9) Press X10 pushbutton in and set oscilloscope calibrator MARKER output to 2 s.
(10) Using horizontal POS control and rotating oscilloscope calibrator EDIT FIELD
knob, align 1 marker per division over center 8 divisions. Oscilloscope calibrator err
display readout indication will be within 5%.
(11) Push horizontal VARIABLE control in and turn fully cw to X1. Press the X100
pushbutton in.
(12) Set oscilloscope calibrator MARKER output for 0.1 ms and rotate oscilloscope
calibrator EDIT FIELD knob for 1 time marker per division over center 8 divisions.
Oscilloscope calibrator err display readout indication will be within 5%.
(13) Press ms and X10 pushbuttons to in.
(14) Set oscilloscope calibrator MARKER output for 10 ms and rotate oscilloscope
calibrator EDIT FIELD knob for 1 time marker per division over center 8 divisions.
Oscilloscope calibrator err display readout indication will be within 5%.
(15) Press X100 pushbutton in and set oscilloscope calibrator MARKER output to 0.1 s.
(16) Rotate oscilloscope calibrator EDIT FIELD knob for 1 time marker per division
over center 8 divisions. Oscilloscope calibrator err display readout indication will be within
5%.
