Appendix 2.3 Commands
*OPT?
Function Queries installed options.
Syntax
*OPT?
Example
*OPT?→EXT1, HARM, DA4, CMP
Description • "NONE" will be attached to the reply if no options
are installed.
• "OPT?" must always be the last query in program
message. If there is another query after this, an error
will occur.
*PSC
Function Selects whether or not to clear the following registers
when turning ON the power, or queries the current
setting. The registers are the standard event enable
register, the extended event enable register and the
transition filter. However, they cannot be cleared if the
parameter is "0".
Syntax
*PSC {<NRf>}
*PSC?
{<NRf>}=0(no clearance), other than
0(clearance)
Example
*PSC 1
*PSC?→1
Description Refer to App 2.4 for more details on the registers.
*RST
Function Resets (initializes) the present settings.
Syntax
*RST
Example
*RST
Description • Refer to 13.2 for initial settings.
*SRE
Function Sets the value of the service request enable register, or
queries the current setting.
Syntax
*SRE {<NRf>}
*SRE?
{<NRf>}=0 to 255
Example *SRE 239
*SRE?→239
Description • Each bit is expressed as a decimal number.
• For example, if "*SRE 239" is set, the service request
enable register will be set to "11101111". This
means that bit 4 of the service request enable register
is disabled, so that bit 5 (ESB0 of the status byte
register will not be set to "1", even if the output
queue is not empty.
• However, bit 6 (MSS) of the status byte register is
the MSS bit, so it will be ignored.
• Default is "*SRE 255", i.e. all bits are enabled.
• The service request enable register will not be
cleared, even if a query is made using *SRE?.
• For details of the service request enable register,
refer to page App2-36.
*STB?
Function Queries the value of the status byte register.
Syntax
*STB?
Example
*STB?→4
Description • Each bit is expressed as a decimal number.
• Bit 6 is RQS and not MSS because the register is
read without serial polling.
• For example, if "*STB 4" is returned, the status byte
register is set to "00000100", i.e. the error queue is
not empty (an error has occurred).
• The status byte register will not be cleared, even if a
query is made using *STB?.
• For details of the status byte register, refer to page
App2-36.
