State
Activates the RF ports alignment function. Setup files with correction data are transfer-
red to the secondary instruments. The following configurations are automatically set.
Correction data is applied during signal generation using these configurations.
●
"RF":
– "Attenuator > Mode = Auto"
– "ALC > Mode = Off (Table)" and "ALC > Driver Amplifier = Auto"
– "UCOR > State = Off"
– "LO Coupling > Mode" = "Internal" or "A Internal & A->B Coupled"
– "LO Coupling > Out State = B On"; otherwise "Out State = Off"
●
"I/Q Mod > Frequency Response":
– "General > Optimization Mode = High Quality Table"
– "General > Optimization Bandwidth = Auto"
– "User Defined Corrections > State = On"
●
"System Configuration > Multi Instrument > Common Trigger":
– "State = On"
– "Multi Instrument Trigger = Primary" on the primary instrument,
"Multi Instrument Trigger = Secondary" on the secondary instruments
●
"System Configuration > Multi Instrument > RF Ports Alignment > RF Ports Setup
Info":
– "Calibration > LO Coupling = Active"
– "Setup Overview > REF Configuration > Signal Source" = "Primary" or "Exter-
nal"
– "Setup Overview > LO Configuration > Signal Source" = "Primary" or "External"
– "Setup Overview > Wiring Constellation" = "Daisy Chain" or "Star"

Setup
Accesses the "Setup File" dialog, that is the standard instrument function for saving
and loading setup files. The provided navigation possibilities in the dialog are self-
explanatory.
The filename and the directory in which the settings are saved are user-definable; the
file extension is predefined.
The setup file (*.rfsa) is an archive file containing setup description file (*.xml), the
RF port correction files (*.rfcor), the frequency response correction files
(*.rfresp) and the S-parameter files (*.snp). It is created automatically during cal-
ibration by RFPAL and can be loaded only in the primary instrument. Do not create
or modify setup files manually.
On recall, the instrument checks if the current instrument is the reference instrument
used during calibration with RFPAL. The dialog also displays the wiring diagram of the
selected setup. If the setup file is loaded in a different instrument, a setting conflict
appears.
The setup files in the secondary instruments are distributed by the primary instrument
and loaded in the secondaries automatically.
