Infiniium V-Series Oscilloscopes Service Guide 17
Running an Environmental Calibration
The environmental calibration uses signals generated in the oscilloscope to
calibrate response. Running an environmental calibration does not invalidate the
oscilloscope’s Certificate of Calibration.
When to perform an environmental calibration:
• You can perform a quick environmental cal rather than a full user cal when
there are changes to the operating environment around the oscilloscope, such
as changes in air flow, temperature, humidity, or the placement of other
instruments near the oscilloscope. For example, you would run the quick
environmental cal if the oscilloscope is moved to a test rack or chamber.
Equipment Required
Procedure
1
Let the oscilloscope warm up before running the environmental calibration.
The environmental calibration should be done only after the oscilloscope has
run for 30 minutes at ambient temperature. Calibration of an oscilloscope that
has not warmed up may result in inaccurate calibration.
2
Choose Utilities > Calibration... .
3
Uncheck the Cal Memory Protect box. You cannot run an environmental
calibration if this box is checked.
NOTE
The oscilloscope must be warmed up (with the oscilloscope application running) for at least
30 minutes at ambient temperature before starting the calibration procedure. Failure to allow
warm up may result in inaccurate calibration.
