For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
Enable and transition registers
(on page E-16). The individual bits of this
register are defined in the following table.
Bit
Value
Description
B0*
status.measurement.instrument.smuX.VOLTAGE_LIMIT
status.measurement.instrument.smuX.VLMT
Set bit indicates that the
voltage limit was exceeded.
Bit B0 decimal value: 1
B1*
status.measurement.instrument.smuX.CURRENT_LIMIT
status.measurement.instrument.smuX.ILMT
Set bit indicates that the
current limit was exceeded.
Bit B1 decimal value: 2
B2-B6
Not used
Not applicable.
B7
status.measurement.instrument.smuX.READING_OVERFLOW
status.measurement.instrument.smuX.ROF
Set bit indicates that an
overflow reading has been
detected.
Bit B7 decimal value: 128
B8
status.measurement.instrument.smuX.BUFFER_AVAILABLE
status.measurement.instrument.smuX.BAV
Set bit indicates that there is
at least one reading stored in
either or both of the dedicated
reading buffers.
Bit B8 decimal value: 256
B9-
B15
Not used
Not applicable.
* This bit will be updated only when a measurement is taken or
smu
X
.source.compliance
is invoked.
As an example, to set bit B0 of the measurement event SMU X summary enable register, set
status.measurement.instrument.smua.enable
=
status.measurement.instrument.smua.VLMT
.
In addition to the above constants,
measurementRegister
can be set to the decimal equivalent of
the bit to set. To set more than one bit of the register, set
measurementRegister
to the sum of
their decimal weights. For example, to set bits B1 and B8, set
measurementRegister
to 258
(which is the sum of 2 + 256).
