Status Subsystem Overview
The Message Available (MAV) summary message from bit 4 is TRUE when there is a message is in the output
queue.
The Status Byte Register is cleared with the *CLS common command. The output queue and the MAV are not
affected by the *CLS command.
Service Request Enable Register The Service Request Enable Register is an 8 bit register that enables
corresponding summary messages in the Status Byte Register. Enabling the service request with the *SRE
command allows you to choose which bits in the Status Byte Register will trigger a service request.
The Service Request Enable Register is read with the *SRE? query. The returned value is the sum of the
binary weighted values of the Service Request Enable Register, with a range of 0 through 63 or 128 through
191.
The value of the unused bit 6 will always be zero.
System Synchronization Bit Bit 12 of the status operation condition register is “pulsed” when the
SYSTem:SYNChronized command is sent. This allows the status system to indicate that:
• the input buffer is synchronized to the point where this command is parsed
• all prior sequential commands are completed
• all prior overlapped commands have started
