BUS:B<x>:RS2
32C:RX:SOUrce?
Arguments
CH1–CH4 specifies an analog channel as the RX source waveform.
D0-D15 specifies a digital channel as the RX source waveform.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
Off sets the specified bus input to off.
BUS:B<x>:RS232C:TX:SOUrce
This command specifies the TX source waveform for the RS-232 bus.
Conditions
This command requires a DPO4COMP application module for 4000 series
models, and an MDO3COMP application module for MDO3000 series models.

Syntax
BUS:B<x>:SPI:BITOrder {LSB|MSB}
BUS:B<x>:SPI:BITOrder?
Arguments
LSB sets the bit order to least significant bit first.
MSB sets the bit order to most significant bit first.
Examples
BUS:B1:SPI:BITORDER LSB sets the bit order to least significant bit first.
BUS:B1:SPI:BITORDER? might return BUS: B1:SPI:BITORDER MSB
indicating the bit order is set to most significant bit first.
