To verify trigger sensitivity

7000 Series Oscilloscopes Service Guide
4 Press the Quick Meas softkey, set the Source softkey to 1,
then press Select and choose Period. Press the Measure
softkey and measure the following:
Period 100 s — The test limits are 99.8 s to 100.2 s.
If the measurements are not within the test limits, go to
the "Troubleshooting" chapter. Then return here.
5 Change the calibrator to 100 ns markers. Change the time
base to 20 ns/div. Adjust the trigger level to obtain a
stable display.
6 Measure the following. If the measurements are not within
the test limits, go to the "Troubleshooting" chapter. Then
return here.
Period 100 ns— The test limits are 99.8 ns to 100.2 ns.
7 Change the time base to 2 ns/div and the calibrator to
5 ns markers.
8 Measure the following. If the measurement is not within
the test limits, go to the "Troubleshooting" chapter. Then
return here.
Period 5 ns — The test limits are 4.96 ns to 5.04 ns.
This test verifies the trigger sensitivity. In this test, you will
apply a sine wave to the oscilloscope at the upper
bandwidth limit. You will then decrease the amplitude of the
signal to the specified levels, and check to see if the
oscilloscope is still triggered.
