32 Agilent 1000A Series Oscilloscopes Service Guide
To test trigger sensitivity
This test verifies the trigger sensitivity. In this test, you apply a sine wave
to the oscilloscope at the bandwidth limits. You then decrease the
amplitude of the signal to the specified levels, and check to see if the
oscilloscope is still triggered.
Table 10 Trigger Sensitivity Specification
Trigger sensitivity Ch 1, 2, 3, 4 (DC
coupling):
≥ 5 mV/div: 1 div from DC to 10 MHz, 1.5 div from 10 MHz to
full bandwidth
< 5 mV/div: 1 div from DC to 10 MHz, 1.5 div from 10 MHz to
20 MHz
