22 7000 Series Oscilloscopes Service Guide
2 Testing Performance
Overview
To completely test and troubleshoot MSO models, create and
use the test connector accessory as described in this chapter.
• The test connector is only required for oscilloscopes that
have the MSO option licensed (enabled).
• The connector is used in the digital channel threshold
accuracy test.
• The test connector keeps electrical distortion to a minimum
and makes it easy for you to connect the oscilloscope probes
to function generators and measurement equipment.
Let the Equipment Warm Up Before Testing
For accurate test results, let the test equipment and the
oscilloscope warm up 30 minutes before testing.
Verifying Test Results
During the tests, record the readings in the Performance Test
Record on page 57. To verify whether a test passes, verify that
the reading is within the limits in the Performance Test Record.
If a performance test fails
If a performance test fails, first perform the User Cal procedure. Press the
following keys to access User Cal: Utility→Service→Start User Cal.
