CALibration Subsystem
These commands control the self-alignment and self-diagnostic processes.
Align All Instrument Assemblies
:CALibration[:ALL]
:CALibration[:ALL]?
Performs an alignment of all the assemblies within the instrument, except for the
tracking generator (Option 1DN), if installed (except Agilent model E7401A).
Before executing this command, connect a cable between front panel connector
AMPTD REF OUT and the INPUT connector for all Agilent EMC analyzers except
Agilent model E7401A.
If the cable is not connected, CAL:ALL will perform a subset of the RF alignment
and a subsequent CAL:RF will be required for the analyzer to meet its specified
performance.
The query performs a full alignment and returns a number indicating the success of
the alignment. A zero is returned if the alignment is successful, even if only a
subset of the RF alignment is performed.

:CALibration:AUTO:MODE ALL|NRF
:CALibration:AUTO:MODE?
This command determines whether or not to include RF alignment as part of the
automatic alignment routines. Eliminating automatic alignment of the RF prevents
changes in the input impedance between sweeps, which could cause input device
instability.
