if you are checking a TPS2012/2014
H
200 MHz
if you are checking TPS2024.
4. Set the oscilloscope VOLTS/DIV to 500 mV/div .
5. Set the oscilloscope SEC/DIV to 10 ns/div .
6. Set the leveled sine wave generator output level to approximately 1 V
p-p
so
that the measured amplitude is approximately 1 V . (The measured amplitude
can fluctuate around 1 V.)
7. Press SET LEVEL TO 50% . Adjust TRIGGER LEVEL as necessary and
then check that triggering is stable.
