(32) Press A/B TRIG to set the A Trigger System on
(the A TRIG CPLG menu will be displayed). Set
REJECT NOISE on.
(31) Press A/B TRIG to set the B Trigger System
on. Select TRIGGER CPLG and set REJECT NOISE
on.
(30) Repeat subparts (6) through (29) for each
VOLTS/DIV setting listed in Table 4-2. Skip subparts
(26) through (29) when checking the last VOLTS/DIV
setting in the table.
(29) Use the VERTICAL POSITION control to set
the bottom of the signal 3 divisions below graticule
center.
(28) Set the Calibration Generator STD AMPLI-
TUDE output level to the corresponding Standard
Amplitude Output Level in Table 4-2.
(27) Set the VOLTS/DIV control to the next position
listed in Table 4-2.
(26) Press the A/B TRIG button to set the A Trigger
System on.
(25) Set the HORIZ MODE to A.
(24) CHECK-That the B Trigger Level readings are
within the limits listed in the "( -) Peak" column under
DC Coupling in Table 4-2.
(23) Set the TRIGGER LEVEL control at the most
negative voltage that produces a barely triggered, jitter-
ing display for the negative (-) setting of the SLOPE
switch.
(22) CHECK-That the B Trigger Level readings
(upper right corner of display) are within the limits listed
in the "(
+)
Peak" column under DC Coupling in
Table 4-2.
(21) Set the TRIGGER LEVEL control at the most
positive voltage that produces a barely triggered, jitter-
ing display for the positive
(+)
setting of the SLOPE
switch.
(20) Set HORIZ MODE to B.
