IEEE 488.2 Common Commands

IEEE 488.2 Common Commands
The instrument supports the following subset of IEEE 488.2 Common Commands, as defined in Chapter 10
of IEEE Standard 488.2–1992. As indicated in the detailed descriptions, some of these commands
correspond directly to instrument front-panel key functionality, while others are available only as remote
commands.

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
