28 :WAVeform Commands
:WAVeform:SOURce:SUBSource
(see page 798)
Command Syntax
:WAVeform:SOURce:SUBSource <subsource>
<subsource> ::= {{SUB0 | RX | MOSI} | {SUB1 | TX | MISO}}
If the :WAVeform:SOURce is SBUS<n> (serial decode), more than one data set
may be available, and this command lets you choose from the available data sets.
When using UART serial decode, this option lets you get "TX" data. (TX is an alias
for SUB1.) The default, SUB0, specifies "RX" data. (RX is an alias for SUB0.)
When using SPI serial decode, this option lets you get "MISO" data. (MISO is an
alias for SUB1.) The default, SUB0, specifies "MOSI" data. (MOSI is an alias for
SUB0.)
If the :WAVeform:SOURce is not SBUS, or the :SBUS<n>:MODE is not UART or
SPI, the only valid subsource is SUB0.
