Checking Performance-222
DSO
Operators
k. Use the Trigger LEVEL control to place the trigger indicator 1
division above the negative peak of the signal while maintaining a
stable triggered display.
I.
Position the waveform vertically to place the top of the signal 1
division below the center horizontal graticule line.
m. CHECK-that the signal remains triggered with the TRIG'D
indicator light on.
n. Disconnect the CH 1 probe tip from the BNC-to-male probe-
tip adapter and connect the CH 2 probe tip.
o. SET: CH 1 Coupling CHI OFF
CH

p. CHECK-that the signal remains triggered while the trigger
point indicator

is on the positive slope when rotating the Trigger
LEVEL control through its range.
q.
Set the Trigger SLOPE to
"-."
r. CHECK-that the signal remains triggered while the trigger
point indicator
"
+
"
is on the negative slope when rotating theTrigger
LEVEL control through its range.
s.
Set the CH 2 VOLTS/DIV to 50 mV.
t. Set the Trigger LEVEL control to position the trigger indicator
(+)
1
division below the positive peak of the signal. (Use the Vertical
POSITION control to bring the peak of the signal on screen to see the
trigger position on the waveform.)
u.
Position the waveform vertically to place the bottom of the sig-
nal 1 division above the center horizontal graticule line.
v. CHECK-that the signal remains triggered with the TRIG'D
indicator light on.
w. Use the Trigger LEVEL control to place the trigger indicator 1
division above the negative peak of the signal.
