Testing Performance
To verify trigger sensitivity
To verify trigger sensitivity
This test verifies the trigger sensitivity. In this test, you will apply 25 MHz to the
oscilloscope. You will then decrease the amplitude of the signal to the specified
levels, and check to see if the oscilloscope is still triggered. You will then repeat
the process at the upper bandwidth limit.
Test limits for the Internal trigger:
1 mV to 5 V/div (dc to max bandwidth): greater of 0.35 div or 2.5 mV
p-p
Test limits for the External trigger:
dc to 25 MHz: <75 mV
p-p
25 MHz to max bandwidth: <150 mV
