6.24 Common Command Group
*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 7-3.
*TRG (TRiGger)
Function Executes single measurement (the same
operation as when SINGLE 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.
• It takes approximately 90 s for the test to
complete. When receiving a response from
the WT3000, set the timeout to a relatively
large value.
*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 5-7.
• The "COMMunicate:OPSE" command is used
to specify the overlap command.
