*OPC (OPeration Complete)
Function Sets bit 0 (OPC bit) of the standard event
register to 1 upon the completion of the
specified overlap command.
Syntax *OPC
Example *OPC
Description • For the description regarding how to
synchronize the program using *OPC, see
page 5-8.
• The "COMMunicate:OPSE" command is used
to specify the overlap command.
• If *OPC is not the last command of the
message, the operation is not guaranteed.
*OPC? (OPeration Complete)
Function ASCII code "1" is returned when the specified
overlap command is completed.
Syntax *OPC?
Example *OPC? -> 1
Description • For the description regarding how to
synchronize the program using *OPC?, see
page 5-8.
• The "COMMunicate:OPSE" command is used
to specify the overlap command.
• If *OPC? is not the last command of the
message, the operation is not guaranteed.
*OPT? (OPTion)
Function Queries the installed options.
Syntax *OPT?
Example *OPT? ->G6,B5,DT,FQ,DA,V1,C2,C7,C5,
CC,FL
Description • The presence or absence of the following is
returned: harmonic measurement (G5),
harmonic computation function (G6), built-in
printer (B5), delta computation (DT),
frequency measurement addition (FQ),
20chDA output (DA), VGA output (V1), RS-
232 communications (C2), USB port (for PC,
C12), Ethernet (C7), USB port (for
peripherals, C5), Cycle by Cycle function
(CC), and flicker measurement (FL).
• If none of the options is installed, an ASCII
code "0" is returned.
• The *OPT? query must be the last query of
the program message. An error occurs if
there is a query after this query.

*PSC (Power-on Status Clear)
Function Sets whether to clear the registers below at
power on or queries the current setting. The
register is cleared when the value rounded to an
integer is a non-zero value.
• Standard event enable register
• Extended event enable register
• Transition filter
Syntax *PSC {<NRf>}
*PSC?
<NRf> = 0 (not clear), non-zero (clear)
Example *PSC 1
*PSC? -> 1
Description For details on the registers, see chapter 7.
*RST (ReSeT)
Function Initializes the settings.
Syntax *RST
Example *RST
Description • Also clears *OPC and *OPC? commands that
have been sent earlier.
• All settings except communication settings
are reset to factory default values.
*SRE (Service Request Enable register)
Function Sets 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 • Specify the value as a sum of decimal values
of each bit.
• For example, specifying "*SRE 239" will
cause the service request enable register to
be set to "11101111." In this case, bit 4 of the
service request enable register is disabled
which means that bit 4 (MAV) of the status
byte register is not 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.
• The default value is "*SRE 0" (all bits
disabled).
• A query using *SRE? will not clear the
contents of the service request enable
register.
• For details on the service request enable
register, see page 7-3.
