a. Performance Check
(1) Position controls as listed in (a) through (h) below:
(a) NON STORE pushbutton pressed.
(b) A TIME/DIV switch to 1 ms.
(c) B TIME/DIV AND DELAY TIME switch to 5 s.
(d) DELAY TIME POSITION control to 1.00.
(e) VOLTS/DIV switches to .5.
(f) VERT MODE CH 1 pushbutton pressed and CH 2 released.
(g) Press HORIZ DISPLAY ALT pushbutton.
(h) B (DLY'D) TRIGGER source switch to STARTS AFTER DELAY.
(2) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 to CH 1 input,
through 50Ω feedthrough termination.
(3) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 1 ms and
adjust TI POSITION control so sweep starts at left vertical graticule line. If intensified
portion of A SWEEP does not begin at start of 2d time marker and pulse displayed on B
DLY'D trace does not start at beginning of sweep, perform b (1) below.
(4) Adjust DELAY TIME POSITION control to 9.00. If intensified portion of sweep
does not begin at start of 10th time marker and pulse displayed on B DLY'D trace does not
start at beginning of sweep, perform b (2) below.
(5) Press HORIZ -DISPLAY A pushbutton and adjust DELAY TIME POSITION
control fully ccw. Rotate oscilloscope calibrator knob located below EDIT FIELD
pushbutton for 1 time marker per division. Oscilloscope calibrator Err display readout will
be within 2%, if not, perform b (3) below.
(6) Press X10 MAG pushbutton to X10 and set oscilloscope calibrator for a CHAN
1, MARKER mode output of .1 ms. Rotate oscilloscope calibrator knob located below EDIT
FIELD pushbutton for 1 marker
per division. If
oscilloscope calibrator Err display readout
is not within 3%, perform b (4) below.
(7) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 5 ms and
adjust horizontal position control to position a time marker to vertical graticule centerline.
Release X10 MAG pushbutton. If time marker is not aligned with vertical graticule
centerline within 1 minor division, perform b (5) below.
(8) Position controls as listed in (a) through (d) below:
(a) HORIZ DISPLAY B DLY'D pushbutton pressed.
(b) A TIME/DIV switch to 2 ms.
(c) B TIME/DIV switch to 1 ms.
(d) B (DLY'D) TRIGGER switch to NORM.
(9) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 1 ms and
rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton for 1 time
marker per division. If oscilloscope calibrator Err display readout is not within 2%,
perform b (6) below.
