Testing Performance 2
7000 Series Oscilloscopes Service Guide 29
To verify digital channel threshold accuracy (MSO models only)
This test verifies the digital channel threshold accuracy
specification of the Agilent 7000 Series Oscilloscopes.
Threshold accuracy test limits = ±(100 mV + 3% of threshold
setting)
When to Test
You should perform this test every 12 months or after 2000
hours of operation, whichever comes first.
What to Test
Use these instructions to test the threshold settings of digital
channels D7-D0. Then, use the same instructions to test digital
channels D15-D8.
Verifying Test Results
After each threshold test, record the voltage reading in the
Performance Test Record on page 57. To verify whether a test
passes, verify that the voltage reading is within the limits in the
Performance Test Record.
