:TRIGger:SPI:TIMeout
Syntax
:TRIGger:SPI:TIMeout <time_value>
:TRIGger:SPI:TIMeout?
Description
Set or query the timeout value when the trigger condition is TIMeout in SPI trigger. The
default unit is s.
Parameter
Name
<time_value>
Return The query returns the timeout value in scientific notation.
Format
Example :TRIGger:SPI:TIMeout 0.001

Command
:TRIGger:SPI:SLOPe
Syntax
:TRIGger:SPI:SLOPe <slope>
:TRIGger:SPI:SLOPe?
Description
Set or query the clock edge in SPI trigger.
Parameter
Name
<slope>
Explanation
POSitive: sample the SDA data on the rising edge of the clock.
NEGative: sample the SDA data on the falling edge of the clock.
Return
The query returns POS or NEG.

:TRIGger:SPI:SLOPe POSitive
:TRIGger:SPI:CLEVel
Syntax
:TRIGger:SPI:CLEVel <level>
:TRIGger:SPI:CLEVel?
Description
Set or query the trigger level of the SCL channel in SPI trigger. The unit is the same as the
current amplitude unit.
Parameter
Name
<level>
Explanation
For VerticalScale, refer to :CHANnel<n>:SCALe. For OFFSet, refer
to :CHANnel<n>:OFFSet.
Return
The query returns the trigger level in scientific notation.
