The first few pages of this chapter contain common
commands specified in IEEE Standard 488.2- 1992, IEEE
Standard Codes, Formats, Protocols and Common
Commands for Use with ANSI/IEEE Std 488.1- 1987. New

Following these commands, the Agilent N9340B spectrum
analyzers SCPI commands are listed.
Clear Status
*CLS
Clears the status byte register. It does this by emptying the
error queue and clearing all bits in all of the event registers.
The status byte register summarizes the states of the other
registers. It is also responsible for generating service requests.
Remark:
See *STB?
Standard Event Status Enable
*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.
The query returns the state of the standard event status
enable register.
Range:
Integer, 0 to 255
Example:
*ESE 36 Enables the Standard Event Status Register to
monitor query and command errors (bits 2 and 5).
*ESE? Returns a 36 indicating that the query and command
status bits are enabled.
