Press
INPUT:
3. Set the 5500A to source a 5 MHz leveled sine wave of 100 mV peak-to-peak
(SCOPE output, MODE levsin).
4. Adjust the amplitude of the sine wave to 0.5 division on the display.
5. Verify that the signal is well triggered.
If it is not, press
adjustment; adjust the trigger level and verify that the signal will be triggered now.
The trigger level is indicated by the trigger icon ( ).
6. Set the 5500A to source a 25 MHz leveled sine wave of 400 mV peak-to-peak.
7. Adjust the amplitude of the sine wave 1.5 divisions on the test tool display.
8. Verify that the signal is well triggered.
If it is not, press
adjustment; adjust the trigger level and verify that the signal will be triggered now.
9. Set the 5500A to source a 40 MHz leveled sine wave of 1.8V peak-to-peak.
10. Adjust the amplitude of the sine wave to exactly 4 divisions on the test tool display.
11. Verify that the signal is well triggered.
If it is not, press
adjustment; adjust the trigger level and verify that the signal will be triggered now.
12. When you are finished, set the 5500A to Standby.
