For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to Status register set
contents (on page 12-1) and Enable and transition registers (on page 12-19). The individual bits of
this register are defined in the following table.
status.MEASUREMENT_SUMMARY_BIT
status.MSB
Set summary bit indicates that an enabled event in the Measurement Event Register
has occurred.
Bit B0 decimal value: 1
status.SYSTEM_SUMMARY_BIT
status.SSB
This bit is only available on 2601B, 2602B, 2611B, 2612B, 2635B, and 2636B. Set summary bit
indicates that an enabled event in the System Summary Register has occurred.
Bit B1 decimal value: 2
status.ERROR_AVAILABLE
status.EAV
Set summary bit indicates that an error or status message is present in the error queue.
Bit B2 decimal value: 4
status.QUESTIONABLE_SUMMARY_BIT
status.QSB
Set summary bit indicates that an enabled event in the Questionable Status Register
has occurred.
Bit B3 decimal value: 8
status.MESSAGE_AVAILABLE
status.MAV
Set summary bit indicates that a response message is present in the output queue.
Bit B4 decimal value: 16
status.EVENT_SUMMARY_BIT

Set summary bit indicates that an enabled event in the Standard Event Status Register
has occurred.
Bit B5 decimal value: 32
status.OPERATION_SUMMARY_BIT
status.OSB
Set summary bit indicates that an enabled event in the Operation Status Register has occurred.
Bit B7 decimal value: 128
As an example, to set bit B0 of the service request enable register, set status.request_enable =
status.MSB.
In addition to the above values, requestSRQEnableRegister can be set to the numeric equivalent
of the bit to set. To set more than one bit of the register, set requestSRQEnableRegister to the
sum of their decimal weights. For example, to set bits B0 and B7, set
requestSRQEnableRegister to 129 (1 + 128).
