(3) Adjust horizontal POSITION control and rotate oscilloscope calibrator EDIT
FIELD knob to align 1 time marker per division over center 8 divisions. If oscilloscope
calibrator err display readout does not indicate within r3%, perform b (1) below:
(4) Push SECONDS/DIV CAL control in and set SECONDS/DIV switch to 1 Ps.
(5) Set oscilloscope calibrator MARKER output to 1 Ps.
(6) Adjust horizontal POSITION control and rotate oscilloscope calibrator EDIT
FIELD knob to align 1 time marker per division over the center 8 divisions. If oscilloscope
calibrator err display readout does not indicate within r2%, perform b (2) below.
(7) Set SECONDS/DIV switch to .2 Ps.
(8) Set oscilloscope calibrator MARKER output to 0.2 Ps.
(9) Adjust horizontal POSITION control and rotate oscilloscope calibrator EDIT
FIELD knob to align 1 time marker per division over center 8 divisions. If oscilloscope
calibrator err display readout does not indicate within r3%, perform b (2) below.
(10) Repeat technique of (7) through (9) above for oscilloscope calibrator and TI
SECONDS/DIV switch settings and indications listed in table 4. Oscilloscope calibrator
err display will indicate within percent of error specified.
