7000 Series Oscilloscopes Service Guide
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)
You should perform this test every 12 months or after 2000
hours of operation, whichever comes first.
Use these instructions to test the threshold settings of digital
channels D7- D0. Then, use the same instructions to test
digital channels D15- D8.
After each threshold test, record the voltage reading in the
Performance Test Record on
test passes, verify that the voltage reading is within the
limits in the Performance Test Record.
