All but RF
Immediately executes an alignment of all subsystems except the RF subsystem. The instrument will stop
any measurement currently underway, perform the alignment, and then restart the measurement from the
beginning (similar to pressing the Restart key). This can be used to align portions of the instrument that
are not impacted by an interfering user input signal.
This operation might be chosen instead of
All if you do not want the device under test to experience a
large change in input impedance, such as a temporary open circuit at the analyzer input.
The query form of the remote commands (:CALibration:NRF?) will invoke the alignment and return a
success or failure value.
Successful completion of Align Now, All but RF will clear the “Align Now, All required” Error
Condition, and clear bit 14 in the Status Questionable Calibration register. If “Align Now, All required”
was in effect prior to executing the All but RF, the Error Condition message “Align Now, RF required” is
generated and bit 12 in the Status Questionable Calibration register is set. It will also begin the elapsed
time counter for Last Align Now, All Time, and capture the Last Align Now, All Temperature.
Align Now, All but RF can be interrupted by pressing the Cancel (ESC) front-panel key or remotely with
Device Clear followed by the :ABORt SCPI command. When this occurs the Error Condition message
“Align Now, All required” is generated, and bit 14 is set in the Status Questionable Condition register.
This is because new alignment data may be used for an individual subsystem, but not a full new set of
data for all subsystems.
Couplings: Initializes the time for the Last Align Now, All Time.
Records the temperature for the Last Align Now, All Temperature.
If Align RF component succeeded, initializes the time for the Last Align Now,
RF Time.
If Align RF component succeeded, records the temperature for the Last Align
Now, RF Temperature.
Status Bits/OPC dependencies: Bits 11, 12, or 14 may be set in the Status Questionable Calibration register.
Initial S/W Revision: Prior to A.02.00
Mode: All
Remote Command: *CAL?
Example: *CAL?
Notes: *CAL? returns 0 if successful
*CAL? returns 1 if failed
:CALibration[:ALL]? is the same as *CAL?
See additional remarks described with :CALibration[:ALL]?
Everything about :CALibration[:ALL]? is synonymous with *CAL? including
all conditions, status register bits, and couplings
