:SBUS:I2C:DATA
Command format：

:SBUS:I2C:DATA <value>
:SBUS:I2C:DATA?
Functional description：

This command is used to set I2C bus data. Binary character string data presented by parameter is 0 , 1 or X.
X represents it is unsure. And its rang is related to the value set by instruction setting value
*8bits :SBUS:I2C:DATA:LEN , the rang is 0x0~0xFFFFFFFFFFFFFFFF.
Return format：

Query returns binary character string data.
For example：

:SBUS:I2C:DATA "X00X00X1"
:SBUS:I2C:DATA?
:SBUS:I2C:QUALifier
Command format：

:SBUS:I2C:QUALifier {STARt | RESTart | STOP | LOSS | ADDRess | DATA | ADATA}
:SBUS:I2C:QUALifier?
Functional description：

This command is used to set I2C bus trigger condition of the oscilloscope.
Return format：

Query returns {STARt | RESTart | STOP | LOSS | ADDRess | DATA | ADATA}.
For example：

:SBUS:I2C:QUALifier STOP
:SBUS:I2C:QUALifier?
