H 100 MHz if you are checking a TDS1012B, TDS2012B, TDS2014B,
TDS2022B, or TDS2024B
9. Set the oscilloscope SEC/DIV to 5ns/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. Push SET TO 50%. Adjust TRIGGER LEVEL as necessary and then
check that triggering is stable.
12. For the TDS2022B and TDS2024B models, set the frequency to 200 MHz,
and increase the amplitude to 1 Vp--p. Verify stable triggering.
13. Set the oscilloscope SEC/DIV to 2.5 ns/div.
14. Change the oscilloscope setup using the following step:
Push menu button Select menu option Select setting
TRIGGER Slope Falling
15. Push SET TO 50%. Adjust TRIGGER LEVEL as necessary and then
check that triggering is stable.
16. Disconnect the test setup.
17. Repeat steps 1 through 16 until all input channels have been checked.
This test checks the edge trigger sensitivity for the external trigger.
