Usage
questionableRegister = status.questionable.instrument.smuX.condition
questionableRegister = status.questionable.instrument.smuX.enable
questionableRegister = status.questionable.instrument.smuX.event
questionableRegister = status.questionable.instrument.smuX.ntr
questionableRegister = status.questionable.instrument.smuX.ptr
status.questionable.instrument.smuX.enable = questionableRegister
status.questionable.instrument.smuX.ntr = questionableRegister
status.questionable.instrument.smuX.ptr = questionableRegister
questionableRegister
The questionable status SMU X summary register's status. A zero (0)
indicates no bits set (also send 0 to clear all bits); other values indicate various
bit settings
X
Source-measure unit (SMU) channel (for example
status.questionable.instrument.smua.enable applies to SMU
channel A)
Details
These attributes are used to read or write to the questionable status instrument SMU X summary registers.
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 B0, and the most significant bit is Bit B15. For
example, if a value of 7.68000e+02 (which is 768) is read as the value of the condition register, the binary
equivalent is 0000 0011 0000 0000. This value indicates that bit B8 and bit B9 are set.
