6 RLC Swept SA Measurement Front-Panel & SCPI Reference
System
Key Path System, Alignments, Align Now
Mode All
Remote Command :CALibration:RF
:CALibration:RF?
Example :CAL:RF
Notes :CALibration:RF? returns 0 if successful
:CALibration:RF? returns 1 if failed (including interfering user signal)
While Align Now, RF is performing the alignment, bit 0 in the Status Operation register is set.
Completion, or termination, will clear bit 0 in the Status Operation register.
This command is sequential; it must complete before further SCPI commands are processed.
Interrupting the alignment from remote is accomplished by invoking Device Clear followed by the
:ABORt command.
Successful completion clears the Error Conditions “Align skipped: 50 MHz interference” and
“Align skipped: 4800 MHz interference” and the Error Conditions “Align RF failed” and “Align
Now, RF required”, and clears bits 3, 11, and 12 in the Status Questionable Calibration register.
A failure encountered during alignment will generate the Error Condition message “Align RF
failed” and set bit 3 in the Status Questionable Calibration register.
An interfering user signal will result in bits 11 and 12 to be set in the Status Questionable
Calibration register to indicate Align Now, RF is required.
An interfering user supplied signal will result in the instrument requiring an Align Now, RF with
the interfering signal removed.
Couplings Initializes the time for the Last Align Now, RF Time.
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
External Mixer
Immediately executes an alignment of the External Mixer that is plugged into the USB port. The
instrument stops any measurement currently underway, performs the alignment, then restarts the
measurement from the beginning (similar to pressing the Restart key). As this alignment
calibrates the LO power to the mixer, this is considered an LO alignment; and failure is classified
as an LO alignment failure.
The query form of the remote commands (:CALibration:EMIXer?) will invoke the alignment of the
External Mixer and return a success or failure value.
