Alignments
The Alignments Menu controls and displays the automatic alignment of the instrument, and provides the
ability to restore the default alignment values.
The current setting of the alignment system is displayed in the system Settings Panel along the top of the
display, including a warning icon for conditions that may cause specifications to be impacted.

Align Now
Accesses alignment processes that are immediate action operations. They perform complete operations
and run until they are complete.

All (Daily use)
Immediately executes an alignment of all subsystems which includes both the source and the analyzer in
the TRX module. The “All” alignment is sufficient to maintain specified performance, provided that (1) the
TRX’s internal temperature has not drifted more than +/–5 degree C since the previous alignment, and (2)
no more than 8 hours have elapsed since the previous “All” alignment., and (3) no more than 1 week has
elapsed since these three alignments have all been run: IF, RF, and Source, and (4) a 45 minute warm-up
period between power-up of the TRX and invoking the “All” alignment. The instrument stops any
measurement currently underway, performs the alignment, then restarts the measurement from the
beginning (similar to pressing the Restart key).
If an interfering user signal is present at the RF Input, the alignment is performed on all subsystems except
the RF. After completion, the Error Condition message “Align skipped: 50 MHz interference” or “Align
skipped: 4.8 GHz interference” is generated. In addition the Error Condition message “Align Now, RF
required” is generated, and bits 11 and 12 are set in the Status Questionable Calibration register.
The query form of the remote commands (:CALibration[:ALL]? or *CAL?) invokes the alignment of all
subsystems and returns a success or failure value. An interfering user signal is not grounds for failure; if the
alignment was able to succeed on all portions but unable to align the RF because of an interfering signal,
the resultant will be the success value.
Successful completion of Align Now, All will clear the “Align Now, All required” Error Condition, and clear
bit 14 in the Status Questionable Calibration register. It will also begin the elapsed time counter for Last
Align Now, All Time, and capture the Last Align Now, All Temperature.
