Align Now, 30 MHz to 3.6 GHz
Immediately executes an alignment of the receiver subsystem. The receiver will stop any measurement
currently underway, perform the alignment, and then restart the measurement from the beginning
(similar to pressing the Restart key).
The query form of the remote commands (:CALibration:RFPSelector:RADiated?) will invoke the
alignment of the RF Preselector on Radiated Band and return a success or failure value. Successful
completion will clear the “Align 30 MHz to 3.6 GHz required” Error Condition, and clear the bit 2 in the
Status Questionable Calibration Extended Needed register. The elapsed time counter will begin for Last
Align Now, Radiated Time, and the temperature is captured for the Last Align Now, Radiated
Temperature. The alignment 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 “Align 30 MHz to 3.6 GHz required” is set because new alignment data may be employed for
an individual subsystem, but not a cohesive set of data for all subsystems.
The “Align 30 MHz to 3.6 GHz required” Error Condition will appear when this alignment has expired.
User is now responsible to perform the Align Now, 30 MHz to 3.6 GHz in order to keep the receiver in
warranted operation. This alignment can only be performed by user as it is not part of the Auto Align
process.
Status Bits/OPC Dependencies: Bit 8 or 9 may be set in the Status Questionable Calibration register.
Bit 1 may be set in the Status Questionable Calibration Extended Needed
register.
Bit 0 may be set in the Status Questionable Calibration Extended Failure
register.
