Testing Performance

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:

<10 mV/div (dc to max bandwidth): greater of 1 div or 5 mV

p-p

≥10 mV/div (dc to max bandwidth): 0.6 div

Test limits for the External trigger:

dc to 100 MHz: <100 mV

p-p

100 MHz to max bandwidth: <200 mV
