Full performance verification for the MXR-Series oscilloscopes consists of three
main procedures:
1 Performing the internal oscilloscope self-tests to ensure that the measurement
system is functioning properly. To perform the self-tests, click Utilities > Self
Test.... Then select Scope SelfTest from the Available Self Test drop-down list
box, click Start, and follow the on-screen instructions. If any of the self tests fail,
ensure that the failure is diagnosed and repaired before calibrating and testing
performance.
2 Calibrating the oscilloscope, as described in Chapter 5, “Calibrating the
Oscilloscope,” starting on page 59.
3 Testing the oscilloscope to ensure that it is performing to specification. This
chapter describes these performance test procedures.
