6.24 Common Command Group
*STB?(STatus Byte)
Function Queries the status byte register.
*STB?
Syntax
*STB? -> 4
Example
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)

Example
