6000L Series Oscilloscopes Service Guide 41
To verify trigger sensitivity
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.
Test limits for:
• Internal trigger:
• < 10 mV/div: greater of 1 div or 5 mV
pp
>=10 mV/div: 0.6 div
• External trigger:
1 GHz and 500 MHz models:
(DSO6104L/6054L)
DC to 500 MHz: < 500 mV
pp
100 MHz models:
(DSO6014L)
DC to 100 MHz: < 500 mV
