Performance Verification Procedures
Before beginning these procedures, two conditions must first be met:
The oscilloscope must have been operating continuously for ten minutes in
an environment the meets the operating range specifications for temperature
and humidity.
You must perform the Compensate Signal Path operation described on page
2–21. If the operating temperature changes by more than 10° C, you must
perform the Compensate Signal Path 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.
This procedure uses internal routines to verify that the oscilloscope functions and
