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

All
(In MXE the key label is “All (plus RF Presel 20 Hz – 3.6 GHz)”)Immediately executes an alignment of all
subsystems In MXE, the Align Now All is followed by additionally aligning the RF Preselector section, so in
MXE, the key label contains the parenthetical note “(plus RF Presel 20 Hz – 3.6 GHz)”. 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.
In the MXE, successful completion will also clear the “Align 20 Hz to 30 MHz required” Error Condition, the
“Align 30 MHz to 3.6 GHz required” Error Condition, andthe “Align 20 Hz to 3.6 GHz required” Error
Condition, and clear bits 1 and bit 2 and clear the bit 1 in the Status Questionable Calibration Extended
Needed register.
If the Align RF subsystem succeeded in aligning (no interfering signal present), the elapsed time counter
begins for Last Align Now, RF Time, and the temperature is captured for the Last Align Now, RF
Temperature. In addition the Error Conditions “Align skipped: 50 MHz interference” and “Align skipped: 4.8
