(a) VERTICAL MODE CH 1 BOTH CH 2 to CH 1.
(b) CH 1 and CH 2 VOLTS/DIV to 2m.
(c) A AND B SEC/DIV to .05 s.
(16) Set oscilloscope calibrator for a CHAN 1, EDGE mode output of 10 mV at a
(17) Adjust TI CH 1 ⇕ POSITION control to position top of displayed waveform to
center horizontal graticule line. If square wave aberrations are not within limits specified
in first row of table 5, perform b (83) through (91) below.
(18) Repeat technique of (15) (b), (16) and (17) above for settings and outputs listed in
table 5. If
square wave aberrations are not within
limits specified in
table 5, perform b (83)
through (91) below.
