TRIGger:A:SOURce:SPI <SpiSource>
Selects the MOSI or the MISO line as trigger source. Only relevant, if both lines are
used and configured.
Parameter:
<SpiSource> MOSI | MISO
TRIGger:A:SPI:MODE
<Mode>
Specifies the trigger mode for the SPI protocols (with and without CS).
Parameter:
<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.
PATTern
Sets the trigger event to a serial pattern. To define the pattern,
use TRIGger:A:SPI:PATTern.
For a complete configuration of the pattern mode, you also have
to set TRIGger:A:SPI:PLENgth and TRIGger:A:SPI:
POFFset.
*RST:
BSTart
TRIGger:A:SPI:PATTern <DataPattern>
Defines the bit pattern as trigger condition. The pattern length is adjusted to the num-
ber of bits defined in the pattern.
Parameter:
<DataPattern> String with max. 32 characters (4 byte + 8 bit) . Characters 0, 1
and X are allowed.
Beispiel:
TRIG:A:SPI:PATT "0011XXXX0110"
Sets a 12bit pattern.
