For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to Status register set
contents (on page 15-1) and Enable and transition registers (on page 15-19). The individual bits of
this register are defined in the following table.
status.measurement.instrument.smua.VOLTAGE_LIMIT
status.measurement.instrument.smua.VLMT
Set bit indicates that the voltage limit was exceeded.
Bit B0 decimal value: 1
status.measurement.instrument.smua.CURRENT_LIMIT
status.measurement.instrument.smua.ILMT
Set bit indicates that the current limit was exceeded.
Bit B1 decimal value: 2
status.measurement.instrument.smua.PROTECTION
status.measurement.instrument.smua.PROT
Set bit indicates that the pulser protection was tripped. Refer to
smua.pulser.protect.tripped for events that can trip the protection circuits.
Bit B0 decimal value: 8
status.measurement.instrument.smua.READING_OVERFLOW
status.measurement.instrument.smua.ROF
Set bit indicates that an overflow reading has been detected.
Bit B7 decimal value: 128
status.measurement.instrument.smua.BUFFER_AVAILABLE
status.measurement.instrument.smua.BAV
Set bit indicates that there is at least one reading stored in either or both dedicated
reading buffers.
Bit B8 decimal value: 256
* This bit is updated only when a measurement is made or smua.source.compliance is invoked.
As an example, to set bit B0 of the measurement event SMU A 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).
