To Verify Trigger Sensitivity - Agilent Technologies 6000 Series Service Manual

To verify trigger sensitivity

6000 Series Oscilloscopes Service Guide
8 Make the following measurements. If the measurements are
not within the test limits, go to the "Troubleshooting"
chapter. Then return here.
a For 300 MHz, 500 MHz, and 1 GHz models, period 5 ns —
the test limits are 4.96 ns to 5.04 ns.
b For 100 MHz models, period 10 ns — the test limits are 9.93
ns to 10.07 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.
The internal trigger sensitivity test is mandatory because it is a
specification. The external trigger test is optional because it is a
characteristic, not a specification.
