Command Groups
Table 2-18: Bus Commands (cont.)
Commands Description
BUS:UPPerthreshold{:MATH|:
MATH1}
This command specifies the upper threshold for the math waveform.
BUS:UPPerthreshold:REF<x> This command sets the upper threshold for each reference waveform.
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.

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 Function 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 mixed domain oscilloscope models with RF enabled.
CALibrate:FACtory:STATus:SCOPE? Returns the factory calibration status value saved in nonvolatile m emory for the non-RF
portion of the oscilloscope.
CALibrate:INTERNal Starts a signal path compensation
CALibrate:INTERNal:STARt Starts the internal signal path calibration.
CALibrate:INTERNal:STATus? Returns the current status of the internal signal path calibration.
CALibrate:INTERNal:STATus:RF? This query returns the status of the last SPC run for the RF portion of the instrument:
(doesn't include the analog channels).
Available on mixed domain oscilloscope models with RF enabled.
CALibrate:INTERNal:STATus:
SCOPE?
This query returns the status of the last SPC run for the oscilloscope portion of the
instrument (doesn't include the RF portion).
CALibrate:RESults? Returns the status of all calibration subsystems without performing an SPC operation.
CALibrate:RESults:FACtory? Returns the status of internal and factory calibration.
CALibrate:RESults:FACtory:AFG? This query returns the factory calibration status for the Arbitrary Function Generator portion
of the instrument, if present.
CALibrate:RESults:FACtory:RF? This query returns the factory calibration status for the RF portion of the instrument,
if present.
Available on mixed domain oscilloscope models with RF enabled.
