*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

operation as when SINGLE is pressed).
Syntax

Example
*TRG
Description The multi-line message GET (Group Execute
Trigger) also performs the same operation as this

*TST?(TeST)
Function
Performs a self-test and queries the result.
Syntax
*TST?
Example

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 this
instrument, set the timeout to a relatively large
value.
