(20) If no adjustments were made in (18) above, display readout will indicate ADJ Δ,
(step) 4, 100 μs, 1 μs.
(21) Change oscilloscope calibrator MARKER mode output to 5 μS/D.
(22) Adjust Δ control ccw until no further movement of B sweep display occurs. Note
position of first time marker of B sweep.
(23) Adjust Δ control cw until 2d time marker of B sweep moves left and aligns with
position noted in (22) above.
NOTE
Movement of ΔREF OR DLY POS control at this point will
(24) Push up and release TRIGGER COUPLING switch. Display readout will
indicate X1, X10, HRZ CTR, (step) 5, 10 μs and two vertical cursors appears on the display.
(25) Change oscilloscope calibrator MARKER mode output to 10 μS/D.
(26) If cursors are not aligned with 2d and 10th vertical graticule lines, adjust
Xl GAIN (R860) (fig 1), and HORZ CTR (R801) (fig 1) to align the two cursors with 2d and
10th vertical graticule line (R).
(27) If TI does not display 1 time marker per division l minor division, adjust
X10 GAIN (R850) (fig. 1) for 1 marker per division (R).
(28) Push up and release TRIGGER COUPLING switch.
Display readout will
indicate ADJ Δ, (step) 6, 10 ms, 100 μs.
(29) Change oscilloscope calibrator MARKER mode output to 10 mS/D and adjust
ΔREF OR DLY POS control to intensify 2d time marker and Δ control to intensify 10th time
marker, and superimpose delayed B sweep time markers within .2 division.
(30) Push up and release TRIGGER COUPLING switch, and position calibration
(31) For each step in table 13 do the following:
(a) Adjust ΔREF OR DLY POS and Δ controls as necessary, to intensify
indicated time markers on the A sweep and superimpose displayed B sweep time markers
within listed limits.
(b) Push up and release TRIGGER COUPLING switch.
(32) After completion of step 16 of table 13 TI display will indicate ADJ Δ, (step) 17, 1 μs.
(33) Adjust TRACE SEP control fully cw.
(34) For each step in table 14 (except step 28) adjust Δ control for listed number of
time markers over center 8 divisions then push up and release TRIGGER COUPLING switch.
