Calibration and Diagnostic Command Group
The Calibration and Diagnostic commands provide information about the
current state of oscilloscope calibration. They also initiate internal signal path
calibration (SPC) or execute diagnostic tests. Commands that are specific to
factory calibration are not described in this manual. Instead, they are described
in the Service Manual Documentation CD-ROM in PDF format. You can also
order a printed copy.
Table 2-19: Calibration and Diagnostic Commands
Command
Description
*CAL? Instructs the oscilloscope to perform self-calibration and returns the oscilloscope self
calibration status.
CALibrate:FACtory:STATus? Returns the factory calibration status value saved in nonvolatile memory.
CALibrate:FACtory:STATus:AFG? Returns the factory calibration status for the Arbitrary F unction Generator portion of the
instrument, if present.
CALibrate:FACtory:STATus:RF? Returns the factory calibration status value saved in nonvolatile memory for the RF portion
of the oscilloscope.
Available on m ixed domain oscilloscope models with R F enabled.
CALibrate:FACtory:STATus:SCOPE? Returns the factory calibration status value saved in nonvolatile memory for the non-RF
