Status Registers
Status Register System
26
The results of a query are evaluated in a similar way. If the
*STB?
command returns a decimal value of 140, (140 = 128
+ 8 + 4) then bit 7 is true, bit 3 is true, and bit 2 is true.
The Status Byte Register
The RQS bit is read and reset by a serial poll. The same bit
position (MSS) is read, non- destructively by the *STB?
command. If you serial poll bit 6 it is read as RQS, but if
you send *STB it reads bit 6 as MSS. For more information
refer to IEEE 488.2 standards, section 11.
