*STB?
Function Queries the Status Byte Register value.
Syntax
*STB?
Example
*STB? -> 4
Description • This command returns a sum of the values of
each bit in decimal format.
• Because the register is read without executing
serial polling, bit 6 is an MSS bit, not an RQS
bit.
• For example, if a value of 4 is returned, this
indicates that the status byte register is set to
00000100. This means that the error queue is
not empty (in other words, an error occurred).
• A query using *STB? will not clear the contents
of the status byte register.
• For information about the status byte register,
see page 5-2.
*TST?

self-test consists of tests of each kind of internal

acquisition memory test and backup memory
test.
• This command returns 0 if the self-test is
successful and 1 otherwise.
