SPI - trigger
To configure the protocol trigger, make sure to set first:
●
TRIGger:A:TYPE to BUS
●
TRIGger:A:SOURce to SBUS1 | SBUS2
TRIGger:A:SOURce:SPI.................................................................................................613
TRIGger:A:SPI:MODE....................................................................................................613
TRIGger:A:SPI:PATTern..................................................................................................614
TRIGger:A:SPI:PLENgth.................................................................................................614
TRIGger:A:SPI:POFFset.................................................................................................614
TRIGger:A:SOURce:SPI <SpiSource>
Selects the MOSI or the MISO line as trigger source. Only relevant, if both lines are
used and configured.
Parameters:
<SpiSource> MOSI | MISO
TRIGger:A:SPI:MODE <Mode>
Specifies the trigger mode for the SPI protocols (with and without CS).
Parameters:
<Mode> BSTart | BEND | NTHBit | PATTern
BSTart
Burst start, sets the trigger event to the start of the frame. The
frame starts when the chip select signal CS changes to the
active state.
BEND
Burst end, sets the trigger event to the end of the message.
NTHBit
Sets the trigger event to the specified bit number. To define the
bit number, use TRIGger:A:SPI:POFFset.
