Bit Value Description
B0
status.operation.CALIBRATING
status.operation.CAL
Set bit indicates that the summary bit of the
status.operation.calibrating
register has been
set.
Bit B0 decimal value: 1
B1-B2 Not used Not applicable
B3
status.operation.SWEEPING
status.operation.SWE
Set bit indicates that the summary bit from the
status.operation.sweeping
register is set.
Bit B3 decimal value: 8
B4 status.operation.MEASURING
status.operation.MEAS
Set bit indicates that the summary bit of the
status.operation.measuring
register is set.
Bit B4 decimal value: 16
B5-B9 Not used Not applicable
B10
status.operation.TRIGGER_OVERRUN
status.operation.TRGOVR
Set bit indicates that the summary bit from the
status.operation.trigger_overrun
register is set.
Bit B10 decimal value: 1,024
B11 status.operation.REMOTE_SUMMARY
status.operation.REM
Set bit indicates that the summary bit of the
status.operation.remote
register is set.
Bit B11 decimal value: 2,048
B12 status.operation.USER Set bit indicates that the summary bit from the
status.operation.user
register is set.
Bit B12 decimal value: 4,096
B13 status.operation.INSTRUMENT_SUMMARY
status.operation.INST
Set bit indicates that the summary bit from the
status.operation.instrument
register is set.
Bit B13 decimal value: 8,192
B14 status.operation.PROGRAM_RUNNING
status.operation.PROG
Set bit indicates that a command or program is running.
Bit B14 decimal value: 16,384
B15 Not used Not applicable
As an example, to set bit B12 of the operation status enable register, set
status.operation.enable =
status.operation.USER
.
In addition to the above constants,
operationRegister
can be set to the numeric equivalent of the bit to set.
To set more than one bit of the register, set
operationRegister
to the sum of their decimal weights. For
example, to set bits B12 and B14, set
operationRegister
to 20,480 (which is the sum of 4,096 + 16,384).

Example 1
operationRegister = status.operation.USER +
status.operation.PROG
status.operation.enable = operationRegister
Sets the USER and PROG bits of the
operation status enable register using
constants.
Example 2
-- decimal 20480 = binary 0101 0000 0000 0000
operationRegister = 20480
status.operation.enable = operationRegister
Sets the USER and PROG bits of the
operation status enable register using a
decimal value.
