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.
Test limits for:
• Internal trigger sensitivity on all models:
• < 10 mV/div: greater of 1 div or 5 mV
pp
• >= 10 mV/div: 0.6 div
• External trigger sensitivity on all models:
• DC to 100 MHz: < 200 mV
pp
• 100 MHz - 200 MHz: < 350 mV
