CALibration Subsystem
CALibration Subsystem
These commands control the self-alignment and self-diagnosti c
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 or 1DQ), if installed .
Before executing this command, connect a cable between front pane l
connector
AMPTD REF OUT
and the INPUT connector for all Agilent ES A
spectrum analyzers except Agilent models E4401B and E4411B . If the
cable is not connected, CAL :ALL will perform a subset of the R F
alignment and a subsequent CAL : RF will be required for the analyzer t o
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 i s
successful, even if only a subset of the RF alignment is performed. .

CALibration :AUTO :MODE ALL1NRF
CALibration :AUTO :MODE ?
This command determines whether or not to include RF alignment a s
part of the automatic alignment routines . Eliminating automati c
alignment of the RF prevents changes in the input impedance betwee n
sweeps, which could cause input device instability.
