The commands in the common command group are independent of the instrument’s functions, and are specified in IEEE 488.2-
1987. There is no front panel key that corresponds to this group.
*CLS
*ESE <Space> <NRf>

*ESR ?
*IDN ?
*OPT ?
*PSC <Space> <NRf>
?
*RST
*SRE <Space> <NRf>

*CLS
Function Clears the standard event register, extended event
register and error queue.
Syntax *CLS
Example *CLS
Description • The output will also be cleared if a *CLS command is
appended after the program message terminator.
• For details on the registers and queues, refer to
appendix 2.4.
*ESE
Function Sets the value for the standard event enable register, or
queries the current setting.
Syntax *ESE {<NRf>}
*ESE?
{<NRf>}=0 to 255
Example *ESE 253
*ESE? → 253
Description • Each bit is expressed as a decimal number.
• For example, if “ *ESE 253 ” is set, the standard
enable register will be set to “ 11111101 ”. This
means that bit 2 of the standard event register is
disabled so that bit 5 (ESB) of the status byte
register will not be set to “ 1 ”, even if a query error
occurs.
• Default is “ *ESE 255 ” , i.e. all bits are enabled.
• The standard event enable register will be cleared
when an inquiry is made using *ESE? .
• For details referring the standard event enable
register, refer to page App2-36.
*ESR?
Function Queries the value of the standard event register and
clears it at the same time.
Syntax *ESR?
Example *ESR? → 32
Description • Each bit is expressed as a decimal number.
• It is possible to ascertain the type of event which has
occurred, while SRQ is occuring.
• For example, if “
*ESR 32 ” is returned, this means
that the standard event register is “00100000” , i.e.
the SRQ has occurred due to a command syntax
error.
• If a query is made using *ESR? , the standard event
register will be cleared.
• For details referring the standard event enable
register, refer to page App2-37.
*IDN?
Function Queries the instrument model.
Syntax *IDN?
Example *IDN? → YOKOGAWA,253503,0,F1.11
Description A reply consists of the following information:
<Model>,<Type>,<Serial No.> and <Firmware
version>
*OPC
Function When *OPC is sent, this command sets bit 0 (the OPC
bit) of the standard event register to “ 1 ”. This
command is not supported by this instrument.
Syntax *OPC
*OPC?
Function When *OPC? is sent, “ 1 ” in (ASCII code) will be
returned. This command is not supported by this
instrument.
Syntax *OPC?
