12-112 Instrument Control Library
• This attribute is used to read or write to the operation SMU event registers.
Remarks
• Reading a status register returns a value. The binary equivalent of the returned value
indicates which register bits are set. The least significant bit of the binary number is
bit 0, and the most significant bit is bit 15.
For example, assume value 17 is returned for the enable register. The binary
equivalent is 0000000000010001. This value indicates that bit B0 (CAL) and bit B4
(MEAS) are set.
• The used bits of the operation SMU event registers are described as follows:
• Bit B0, CAL – Set bit indicates that one or more channels are calibrating.
• Bit B4, MEAS – Bit will be set when taking an overlapped measurement, but it will
not set when taking a normal synchronous measurement.
• Bit B11, PRMPTS – Set bit indicates that command prompts are enabled.
• Bit B12, USER – Set bit indicates that an enabled bit in the operation status user
register is set.
• Bit B14, PROG – Set bit indicates that a program is running.
Details See "Operation Event
Example Sets the MEAS bit of the operation SMU A enable register:
status.operation.instrument.smua.enable = status.operation.MEAS
