Performance verification procedures
Before beginning these procedures, two conditions must be met:
• The oscilloscope must have been operating continuously for twenty minutes within the operating temperature range
specified in the Environmental Performance table.
• You must perform the Self Calibration operation described below. If the ambient temperature changes by more than 5
°C, you must perform the Self Calibration operation again.
The time required to complete the entire procedure is approximately one hour.
Warning: Some procedures use hazardous voltages. To prevent electrical shock, always set voltage source
outputs to 0 V before making or changing any interconnections.
Self test
This internal procedure is automatically performed every time the oscilloscope is powered on. No test equipment or hookups
are required. Verify that no error messages are displayed before continuing with this procedure.
1
The bandwidth test does not have a high limit.
2
The limits vary by model. Check the procedure for the correct limits.
