Attribute Measurement SMU event status register set.
Usage Reads condition, enable, event, NTR and PTR registers:
measreg = status.measurement.instrument.smuX.condition
measreg = status.measurement.instrument.smuX.enable
measreg = status.measurement.instrument.smuX.event
measreg = status.measurement.instrument.smuX.ntr
measreg = status.measurement.instrument.smuX.ptr
Writes to enable, NTR and PTR registers:
status.measurement.instrument.smuX.enable = measreg
status.measurement.instrument.smuX.ntr = measreg
status.measurement.instrument.smuX.ptr = measreg
Set measreg to one of the following values:
0 Clears all bits.
status.measurement.VOLTAGE_LIMIT Sets VLMT bit (B0).
status.measurement.VLMT Sets VLMT bit (B0).
status.measurement.CURRENT_LIMIT Sets ILMT bit (B1).
status.measurement.ILMT Sets ILMT bit (B1).
status.measurement.READING_OVERFLOW Sets ROF (B7).
status.measurement.ROF Sets ROF (B7).
status.measurement.BUFFER_AVAILABLE Sets BAV (B8).
status.measurement.BAV Sets BAV (B8).
measreg can also be set to the decimal weight of the bit to be set. Examples:
To set bit B0 (VLMT), set measreg to 1 (2
0
).
To set bit B1 (ILMT), set measreg to 2 (2
1
).
To set bit B8 (BAV), set measreg to 256 (2
8
).
To set more than one bit of the register, set measreg to the sum of their decimal
weights. For example, to set bits B0 and B8, set
measreg to 257 (1 + 256).
