5.
Set the leveled sine wave generator frequency to
10 MHz
.
6.
Set the leveled sine wave generator output level to approximately
500 mV
p-p
so that the measured amplitude is approximately
500 mV
. (The measured
amplitude can fluctuate around 500 mV.)
7.
Press
SET LEVEL TO 50%
. Adjust
TRIGGER LEVEL
as necessary and
then check that triggering is stable.
8.
Set the leveled sine wave generator frequency to the following:
H
100 MHz
if you are checking a TPS2012/2014
H
200 MHz
if you are checking TPS2024.
9.
Set the oscilloscope SEC/DIV to
10 ns/div
.
10.
Set the leveled sine wave generator output level to approximately
750 mV
p-p
so that the measured amplitude is approximately
750 mV
. (The measured
amplitude can fluctuate around 750 mV.)
11.
Press
SET LEVEL TO 50%
. Adjust
TRIGGER LEVEL
as necessary and
then check that triggering is stable.
