3. Set the leveled sine wave generator frequency to 60 MHz if you are checking
a TDS 210 or to 100 MHz if you are checking a TDS 220 or TDS 224.
4. Set the instrument VOLTS/DIV to 500 mV/div.
5. Set the instrument SEC/DIV to 10 ns/div.
6. 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.)
7. Press SET LEVEL TO 50%. Adjust TRIGGER LEVEL as necessary and
then check that triggering is stable.
8. Change the instrument setup using the following steps:
Press menu button Select menu item Select setting
TRIGGER Slope Falling
9. Press SET LEVEL TO 50%. Adjust TRIGGER LEVEL as necessary and
then check that triggering is stable.
10. Change the instrument setup using the following steps:
Press menu button Select menu item Select setting
