models, and an MDO3EMBD application module for MDO3000 series models.
Group
Bus
Syntax
BUS:B<x>:SPI:DATa:SIZe <NR1>
BUS:B<x>:SPI:DATa:SIZe?
Arguments
NR1 is the data size of the specified bus.
Examples
BUS:B1:SPI:DATA:SIZE 8 sets the data size to 8 bits per word.
BUS:B1:SPI:DATA:SIZE? might return BUS:B1:SPI:DATA:SIZE 8
indicating the data size is 8 bits per word.
BUS:B<x>:SPI:FRAMING
