32 1000 X-Series Oscilloscopes Service Guide
2 Testing Performance
To verify trigger sensitivity
These tests verify the trigger sensitivity. In these tests, you will apply a sine wave
to the oscilloscope at two bandwidths: 10 MHz and the maximum bandwidth of
the oscilloscope. For each sine wave, you will decrease the amplitude of the signal
to a specified level and check to see if the oscilloscope still triggers.
The external trigger sensitivity is also tested in both the 1.6 V and 8 V ranges for
the 70 MHz and 100 MHz (DSOX) models.
