*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, it 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 6-2.
*STB? (STatus Byte)
Function
Queries the status byte register.
Syntax
*STB?
Example
*STB? -> 4
Description • The sum of the bits is returned as a decimal
value.
• Since the register is read without executing
serial polling, bit 6 is a MSS bit not RQS.
• For example, if a value of "4" is returned, this
indicates that the status byte register is set to
"00000100." In this case, you can see that
"the error queue is not empty" (an error
occurred).
• A query using *STB? will not clear the
contents of the status byte register.
• For details on the status byte register, see
page 6-2.
*TRG
(TRiGger)
Function
Executes the same operation as when SINGLE
(SHIFT+HOLD) is pressed.
Syntax
*TRG
Example
*TRG
Description The multi-line message GET (Group Execute
Trigger) also performs the same operation as
this command.

*TST? (TeST)
Function
Performs a self-test and queries the result.
Syntax
*TST?
Example
*TST? -> 0
Description • The self-test involves internal memory tests.
• "0" is returned if the self-test is successful, "1"
if it is not.
*WAI
(WAIt)
Function
Holds the subsequent command until the
completion of the specified overlap operation.
Syntax
*WAI
Example
*WAI
Description • For the description regarding how to
synchronize the program using *WAI, see
page 4-7.
• The "COMMunicate:OPSE" command is used
to specify the overlap command.
