IEEE Common Command s
These commands are specified in IEEE Standard 488 .2-1992, IEEE
Standard Codes, Formats, Protocols and Common Commands for Us e
with ANSI /IEEE Std 488.1-1987. New York, NY11992 .
Calibration Query
Performs a full alignment and returns a number indicating the succes s
of the alignment . A zero is returned if the alignment is successful . The
SCPI equivalent for this command is the same as : CALibrate [ : ALL ] ?
NOTE
Before executing this command, connect a cable between front pane l
connector AMPTD REF OUT and the INPUT connector for all Agilent ESA
spectrum analyzers except Agilent models E4401B and E4411B . Except
for the models indicated that do not require the cable, the alignment
will fail using commands CAL : RF or
Caw :
TG if the cable is not
connected .

Clear Status
Clears the status byte . It does this by emptying the error queue and
clearing all bits in all of the event registers. The status byte registers
summarize the states of the other registers. It is also responsible for
generating service requests.
Remarks : See *STB ?
Standard Event Status Enabl e
*ESE <number >
*ESE ?
Sets the bits in the standard event status enable register . This register
monitors I/O errors and synchronization conditions such as operation
complete, request control, query error, device dependent error,
execution error, command error and power on . A summary bit is
generated on execution of the command .
Query returns the state of the standard event status enable register .
Range : Integer, 0 to 255
