STATUS

*STB?

Query

DESCRIPTION

The *STB? query reads the contents of the 488.1 defined STatus
Byte register (STB), and the Master Summary Status (MSS). The

response represents the values of bits 0 to 5 and 7 of the STB
register and the MSS summary message.

The response to a *STB? query is identical to the response of a
serial poll except that the MSS summary message appears in bit 6

in place of the RQS message. Refer to the table on page 225 for
further details of the status register structure.
