Some common commands are defined in the IEEE 488.2 standard and must be implemented by all SCPI compatible instruments. These commands are identified by the asterisk (*) at the beginning of the command keyword. These commands are defined to control instrument status registers, status reporting, synchronization, and other common functions. The common commands that are supported by the S412E are shown below.
*IDN?
Title
Identification Query
Description
This command returns the following information in <string> format separated by commas: manufacturer name (“Anritsu”), model number/options, serial number, firmware package number. The model number and options are separated by a “/” and each option is separated by a “/”.
For example, the return string might appear as follows:
“Anritsu,MS2028B/10/2,62011032,1.23”
*RST
Title
Reset
Description
This command restores parameters in the current application as well as system settings to their factory default values.
System settings that are affected by this command are Ethernet configuration, language, volume, and brightness. Note that the unit will power cycle after this command is executed.
Front Panel Access:
Shift‑8 (System), System Options, Reset, Factory Defaults
See Also:
:SYSTem:PRESet
Note
The best practice when starting any remote program is to reset the instrument to a known state. This is especially important when the instrument is being used in both remote and front‑panel operation. Use the *RST or the :SYSTem:PRESet command to restore the instrument to the factory default settings.
Operating the instrument through the front panel and remotely at the same time could, under certain conditions, cause the instrument to hang up. To avoid conflicts, do not combine front panel operation and remote operation.
SCPI Required Commands
The required SCPI commands that are supported by the S412E are listed in the Table: SCPI Required Commands. These commands work in all measurement modes and are described in All Mode Commands.
SCPI Required Commands

SCPI Optional Commands
Table: SCPI Optional Commands lists the optional SCPI commands that comprise the majority of the command set that is described in this document. These commands control most of the programmable functions of the S412E.
