Description:
This command allows you to set bits in the Status Byte register. The state is returned as a sum of the
decimal weights of all set bits. The decimal weight for each bit is assigned according to the following
formula:
2
(bit_number)
with acceptable values for bit_number being 0 through 7.
The register is not cleared by this query. To clear the Status Byte register, you must send the *CLS
command.
Bits in the Status Byte register are defined as follows:
Bit 0 summarizes all enabled bits of the User Status register.
Bit 1 is reserved.
Bit 2 summarizes all enabled bits of the Device State register.
Bit 3 summarizes all enabled bits of the Questionable Status register.
Bit 4 is the Message Available (MAV) bit. It is set whenever there is something in the analyzer’s
output queue.
