CAL:FAC:STAT:
SCOPE?
might return CALIBRATE:FACTORY:STATUS:SCOPE
PASS
indicating that factory calibration passed.
CALibrate:INTERNal (No Query Form)
This command starts a signal path compensation.
NOTE. Disconnect or otherwise remove all input signals prior to starting
self-calibration. The self-calibration can take several minutes to complete.

CALibrate:INTERNal
Arguments
None
Examples
CALIBRATE:INTERNAL starts a serial path compensation cycle.
CALibrate:INTERNal:STARt (No Query Form)
This command starts the internal signal path calibration (SPC) of the oscilloscope
– exactly the same as
:CALibrate:INTERnal. First, disconnect all probes
and cables from all channels. You can use the CALibrate:INTERNal:STATus?
query to return the current status of the internal signal path calibration of the
oscilloscope. This query can only be sent when internal calibration (SPC) is
not running.
NOTE. Disconnect or otherwise remove all input signals prior to starting
self-calibration. The self-calibration can take several minutes to complete.

Examples
CALIBRATE:INT
ERNAL:START
initiates the internal signal path calibration of
the oscilloscope.
CALibrate:INTERNal:STATus? (Query Only)
Returns the current status of the oscilloscope internal signal path calibration for
the last SPC operation.
NOTE. Disconnect or otherwise remove all input signals prior to starting
self-calibration. The self-calibration can take several minutes to complete .

*CAL?
Returns
This query will return one of the following:
INIT indicates the oscilloscope has not had internal signal path calibration
run.
PASS indicates the signal path calibration completed successfully.
FAIL indicates the signal path calibrat
ion did not complete successfully.
RUNNING indicates the signal path calibration is currently running.
Examples
CAL:INTERN:STAT? might return :CALIBRATE:INTERNAL:S TATus INIT
indicating that the current status of the internal signal path calibrationisthatit
has not been run.
CALibrate:INTERNal:STATus:RF? (Query Only)
This query returns the status of the last SPC run for the RF portion of the
instrument: (doesn't include the analog channels). This query is synonymous
with

Commands Listed in Alphabetical Order
Returns
This query will
return one of the following:
INIT indicates the RF portion of the instrument has not been calibrated.
PASS indicates the RF internal calibration completed successfully.
RUNNING indicates the oscilloscope internal calibration is currently running.
FAIL indicates the RF internal calibration did not complete successfully.
Examples
CAL:INTERN:STAT:RF? might return INIT indicating that the RF portion of the
instrument has not been internally calibrated.
CALibrate:INTERNal:STATus:SCOPE? (Query Only)
This query returns the status of the last SPC run for the oscilloscope portion of
the instrument (doesn't include the RF portion). To query the status of the RF
portions, use CALibrate:INTERNal:STATus:RF?
This query is synonymous to CALibrate:RESults:SPC:SCOPE?

Returns
Th
is query will return one of the following:
INIT indicates the oscilloscope portion of the instrument has not been calibrated.
PASS indicates the oscilloscope internal calibration completed successfully.
RUNNING indicates the oscilloscope internal calibration is currently running.
FAIL indicates the oscilloscope internal calibration did not complete successfully.
Examples
CAL:INTERN:STAT:SCOPE? might return INIT indicating that the oscilloscope
portion of the instrument has not been calibrated.
CALibrate:RESults? (Query Only)
Returns the status of internal and factory calibrations, without performing any
calibration operations. The results returned do not include the calibration status
of attached probes. The
CALibrate:RESults? query is intended to support
GO/NoGO testing of the oscilloscope calibration readiness: all returned results
should indicate PASS status if the oscilloscope is "fit for duty". It is quite
