Communication Commands 2 (System of Commands Complying to the IEEE 488.2-1992 Standard)
14
*IDN?
Function Queries the instrument model.
Syntax *IDN?
Example *IDN? -> YOKOGAWA,760503,0,F1.01
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?
*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 Section 14.4 for more details on the
registers.
*RST
Function Resets (initializes) the present settings.
Syntax *RST
Example *RST
Description Refer to 12.2 for initial settings. All settings
except communication settings are reset to
factory default values.
*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? -> 175 (since the bit 6 (MSS)
setting is ignored)
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 4 (MAV) of the status byte register will
not be set to “
1
,” even if the output queue is
not empty.
• Bit 6 (MSS) of the status byte register is the
MSS bit itself, and therefore, is 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 14-45.
*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 14-45.
*TRG
Function Executes the same operation as the TRIG
(SHIFT+HOLD) key on the front panel.
Syntax *TRG
Description Executes the same operation as when using the
multi line message GET (Group Execute Trigger).
*TST?
Function Executes a self-test and queries the result. All
internal memory boards are tested.
Syntax *TST?
Example *TST? -> 0
Description “ 0 ” will be returned when the result are
satisfactory. If an abnormality is detected, “ 1 ”
will be returned.
*WAI
Function Waits for the command following *
WAI
until
execution of the designated overlap command
has been completed. This command is not
supported by this instrument.
Syntax *WAI
