Bit
Value and description
B4
status.MESSAGE_AVAILABLE
status.MAV
Set summary bit indicates that a response message is present in the Output Queue.
Bit B4 decimal value: 16
B5
status.EVENT_SUMMARY_BIT
status.ESB
Set summary bit indicates that an enabled standard event has occurred.
Bit B5 decimal value: 32
B6
status.MASTER_SUMMARY_STATUS
status.MSS
Request Service (RQS)/Master Summary Status (MSS). Depending on how it is used, bit B6 of
the status byte register is either the Request for Service (RQS) bit or the Master Summary Status
(MSS) bit:
▪ When using the GPIB, USB, or VXI-11 serial poll sequence of the 2600B to obtain the
status byte (serial poll byte), B6 is the RQS bit. The set bit indicates that the Request
Service (RQS) bit of the status byte (serial poll byte) is set and a service request (SRQ) has
occurred.
▪ When using the status.condition register command or the *STB? common command
to read the status byte, B6 is the MSS bit. Set bit indicates that an enabled summary bit of
the status byte register is set.
Bit B6 decimal value: 64
B7
status.OPERATION_SUMMARY_BIT
status.OSB
Set summary bit indicates that an enabled operation event has occurred.
Bit B7 decimal value: 128
In addition to the above constants, when more than one bit of the register is set, statusByte equals
the sum of their decimal weights. For example, if 129 is returned, bits B0 and B7 are set (1 + 128).

Example
statusByte = status.condition
print(statusByte)
Returns statusByte.
Sample output:
1.29000e+02
Converting this output (129) to its binary equivalent yields 1000 0001
Therefore, this output indicates that the set bits of the status byte condition register are presently B0 (MSS) and
B7 (OSB).
